FIELD OF THE DISCLOSURE

The present disclosure generally relates to a method and apparatus for a radio resources communication management system to adapt to context and usage of communication channels in relation to users having a plurality of available radiofrequency communication devices.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Technology and information handling needs and requirements can vary between different applications. Thus information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, graphics interface systems, data storage systems, and networking systems. Information handling systems can also implement various virtualized architectures. Data communications among information handling systems may be via networks that are wired, wireless, optical or some combination. Users may choose from among several available radiofrequency communication platforms in information handling systems for data and other communications with other users via communication and data networks.

Further, while a single information handling system 100 is illustrated, the term “system” shall also be taken to include any collection of systems or sub-systems that individually or jointly execute a set, or multiple sets, of instructions to perform one or more computer functions.

The disk drive unit 116 may include a computer-readable medium 122 in which one or more sets of instructions 124 such as software can be embedded. Similarly, main memory 104 and static memory 106 may also contain computer-readable medium for storage of one or more sets of instructions, parameters, or profiles 124. The disk drive unit 116 and static memory 106 also contains space for data storage. Further, the instructions 124 may embody one or more of the methods or logic as described herein. For example, instructions relating to the context aware radio resource management system including the concurrent wireless link optimization system software algorithms may be stored here.

In a particular embodiment, the instructions, parameters, and profiles 124 may reside completely, or at least partially, within the main memory 104, the static memory 106, and/or within the disk drive 116 during execution by the processor 102 of information handling system 100. As explained, some or all of the concurrent wireless link optimization system or the context aware radio resource management system may be executed locally or remotely. The main memory 104 and the processor 102 also may include computer-readable media. Battery 114 may include a smart battery system that tracks and provides power state data 126. This power state data may be stored with the instructions, parameters, and profiles 124 to be used with the systems and methods disclosed herein.

The network interface device shown as wireless adapter 120 can provide connectivity to a network 128, e.g., a wide area network (WAN), a local area network (LAN), wireless local area network (WLAN), a wireless personal area network (WPAN), a wireless wide area network (WWAN), or other network. Connectivity may be via wired or wireless connection. Wireless adapter 120 may include one or more radio frequency subsystems 130 with transmitter/receiver circuitry, wireless controller circuitry, amplifiers and other circuitry for wireless communications. Each radiofrequency subsystem 130 may communicate with one or more wireless technology protocols. The radiofrequency subsystem 130 may contain individual subscriber identity module (SIM) profiles for each technology service provider and their available protocols. Alternatively it may have a software based SIM profile that is reconfigurable. In yet another aspect, the radiofrequency subsystem may include an eSIM for electronic control over activate SIM profile being used depending on the results of wireless link optimization analysis for context aware radio resource management system and for concurrent radio operation interference modeling or assessment. The wireless adapter 120 may also include antenna system 132 which may be tunable antenna systems for use with the system and methods disclosed herein.

In some aspects of the present disclosure, one wireless adapter 120 may operate two or more wireless links. In a further aspect, the wireless adapter 120 may operate the two or more wireless links with a single, shared communication frequency band such as with the 5G standard relating to unlicensed wireless spectrum for small cell 5G next gen operation or for unlicensed Wi-Fi WLAN operation in an example aspect. For example, a 5 GHz wireless communication frequency band may be apportioned under the 5G standards for communication on either small cell WWAN wireless link operation or Wi-Fi WLAN operation as described further below. In some embodiments, the shared, wireless communication band may be transmitted through one or a plurality of antennas. Other shared communication frequency bands are contemplated for use with the embodiments of the present disclosure as well.

In other aspects, the information handling system 100 operating as a wireless communication device may operate a plurality of wireless adapters 120 for concurrent radio operation in one or more wireless communication bands. The plurality of wireless adapters 120 may further share a wireless communication band in some disclosed embodiments. The proximity of concurrent radio transmission or reception in a shared band precipitates a need to assess or model interference for concurrently operating wireless communication devices as with the context aware radio resource management system including a concurrent wireless link optimization system of the present disclosure. Similarly, the proximity of concurrent radio transmission or reception in a shared band may further precipitate provide a remedy or adjustment to selected wireless link frequency channels or transmission or reception along those wireless channels in view of the concurrent wireless link optimization system of the present disclosure.

The wireless adapter 120 may operate in accordance with any wireless data communication standards. To communicate with a wireless local area network, standards including IEEE 802.11 WLAN standards, IEEE 802.15 WPAN standards, WWAN such as 3GPP or 3GPP2, or similar wireless standards may be used. Wireless adapter 120 may connect to any combination of macro-cellular wireless connections including 2G, 2.5G, 3G, 4G, 5G or the like from one or more service providers. The wireless adapter 120 can represent an add-in card, wireless network interface module that is integrated with a main board of the information handling system or integrated with another wireless network interface capability, or any combination thereof. In an embodiment the wireless adapter 120 may include one or more radio frequency subsystems 130 including transmitters and wireless controllers for connecting via a multitude of wireless links. In an example embodiment, an information handling system may have an antenna system transmitter 132 for 5G small cell WWAN, Wi-Fi WLAN or WiGig connectivity and one or more additional antenna system transmitters 132 for macro-cellular communication. The radio frequency subsystems 130 include wireless controllers to manage authentication, connectivity, communications, power levels for transmission, buffering, error correction, baseband processing, and other functions of the wireless adapter 120.

The radio frequency subsystems 130 of the wireless adapters may measure various metrics relating to wireless communication pursuant to operation of a context aware radio resource management system as in the present disclosure. For example, the wireless controller of a radio frequency subsystem 130 may manage detecting and measuring received signal strength levels, bit error rates, signal to noise ratios, latencies, jitter, and other metrics relating to signal quality and strength. In one embodiment, a wireless controller may manage one or more radio frequency subsystems 130 within a wireless adapter 120. The wireless controller also manages transmission power levels which directly affect radio frequency subsystem power consumption. To detect and measure power consumption by a radio frequency subsystem 130, the radio frequency subsystem 130 may implement current and voltage measurements of power that is directed to operate a radio frequency subsystem. The voltage and current provides power measurement in milliwatts. Energy consumed may be calculated from sample measurements by taking average power measured over a duration of transmission. In an alternative embodiment of power measurement, counter registers may be used to estimate power consumed during transmissions. Energy measurement may be a sampled during a count cycle. In this case, a sample energy measurement per count is multiplied into a count for operation of a radio subsystem. In this way, power consumption may be estimated in an example embodiment.

The wireless network may have a wireless mesh architecture in accordance with mesh networks described by the wireless data communications standards or similar standards. The wireless adapter 120 may also connect to the external network via a WPAN, WLAN, WWAN or similar wireless switched Ethernet connection. The wireless data communication standards set forth protocols for communications and routing via access points, as well as protocols for a variety of other operations. Other operations may include handoff of client devices moving between nodes, self-organizing of routing operations, or self-healing architectures in case of interruption.

In an alternative embodiment, dedicated hardware implementations such as application specific integrated circuits, programmable logic arrays and other hardware devices can be constructed to implement one or more of the methods described herein. Applications that may include the apparatus and systems of various embodiments can broadly include a variety of electronic and computer systems. One or more embodiments described herein may implement functions using two or more specific interconnected hardware modules or devices with related control and data signals that can be communicated between and through the modules, or as portions of an application-specific integrated circuit. Accordingly, the present system encompasses software, firmware, and hardware implementations.

In accordance with various embodiments of the present disclosure, the methods described herein may be implemented by software programs executable by a computer system. Further, in an exemplary, non-limited embodiment, implementations can include distributed processing, component/object distributed processing, and parallel processing. Alternatively, virtual computer system processing can be constructed to implement one or more of the methods or functionality as described herein.

The present disclosure contemplates a computer-readable medium that includes instructions, parameters, and profiles 124 or receives and executes instructions, parameters, and profiles 124 responsive to a propagated signal; so that a device connected to a network 128 can communicate voice, video or data over the network 128. Further, the instructions 124 may be transmitted or received over the network 128 via the network interface device or wireless adapter 120.

Information handling system 100 includes one or more application programs 124, and Basic Input/Output System and firmware (BIOS/FW) code 124. BIOS/FW code 124 functions to initialize information handling system 100 on power up, to launch an operating system, and to manage input and output interactions between the operating system and the other elements of information handling system 100. In a particular embodiment, BIOS/FW code 124 reside in memory 104, and include machine-executable code that is executed by processor 102 to perform various functions of information handling system 100. In another embodiment (not illustrated), application programs and BIOS/FW code reside in another storage medium of information handling system 100. For example, application programs and BIOS/FW code can reside in drive 116, in a ROM (not illustrated) associated with information handling system 100, in an option-ROM (not illustrated) associated with various devices of information handling system 100, in storage system 107, in a storage system (not illustrated) associated with network channel of a wireless adapter 120, in another storage medium of information handling system 100, or a combination thereof. Application programs 124 and BIOS/FW code 124 can each be implemented as single programs, or as separate programs carrying out the various features as described herein.

While the computer-readable medium is shown to be a single medium, the term “computer-readable medium” includes a single medium or multiple media, such as a centralized or distributed database, and/or associated caches and servers that store one or more sets of instructions. The term “computer-readable medium” shall also include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by a processor or that cause a computer system to perform any one or more of the methods or operations disclosed herein.

In a particular non-limiting, exemplary embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random access memory or other volatile re-writable memory. Additionally, the computer-readable medium can include a magneto-optical or optical medium, such as a disk or tapes or other storage device to store information received via carrier wave signals such as a signal communicated over a transmission medium. Furthermore, a computer readable medium can store information received from distributed network resources such as from a cloud-based environment. A digital file attachment to an e-mail or other self-contained information archive or set of archives may be considered a distribution medium that is equivalent to a tangible storage medium. Accordingly, the disclosure is considered to include any one or more of a computer-readable medium or a distribution medium and other equivalents and successor media, in which data or instructions may be stored.

FIG. 2 illustrates a network 200 that can include one or more information handling systems. In a particular embodiment, network 200 includes networked wireless communication devices 210, 220, and 230, wireless network access points, and multiple wireless connection link options. A variety of additional computing resources of network 200 may include client mobile information handling systems, data processing servers 290, network storage devices, local and wide area networks, or other resources as needed or desired. As specifically depicted, systems 210, 220, and 230 may be a laptop computer, tablet computer, or Smartphone device. These wireless communication devices 210, 220, and 230, may access a wireless local network 240, or they may access a macro-cellular network 250. For example, the wireless local network 240 may be the wireless local area network (WLAN), a wireless personal area network (WPAN), or a wireless wide area network (WWAN). In one example embodiment, a standalone mobile information handling system 210, 220, or 230 may operate on WLAN such as Wi-Fi or on unlicensed WWAN small cell wireless links such as with small cell unlicensed LTE substations in wireless local network 240. Since WPAN or Wi-Fi Direct Connection 248 and WWAN networks can functionally operate similar to WLANs, they may be considered as wireless local area networks (WLANs) for purposes herein. Components of a WLAN may be connected by wireline or Ethernet connections to a wider external network. For example, wireless network access points may be connected to a wireless network controller and an Ethernet switch. Wireless communications across wireless local area network 240 may be via standard protocols such as IEEE 802.11 Wi-Fi, IEEE 802.11ad WiGig, IEEE 802.15 WPAN, or emerging 5G small cell WWAN communications such as eNodeB, or similar wireless network protocols. Alternatively, other available wireless links within network 200 may include macro-cellular connections 250 via one or more service providers 260 and 270. Service provider macro-cellular connections may include 2G standards such as GSM, 2.5G standards such as GSM EDGE and GPRS, 3G standards such as W-CDMA/UMTS and CDMA2000, 4G standards, or emerging 5G standards including small cell WWAN, WiMAX, LTE, and LTE Advanced, LTE-LAA, and the like.

In some embodiments according to the present disclosure, a networked wireless communication device 210, 220, or 230 may have a plurality wireless network interface systems capable of transmitting simultaneously within a shared communication frequency band. That communication within a shared communication frequency band may be sourced from different protocols on parallel wireless network interface systems or from a single wireless network interface system capable of transmitting and receiving from multiple protocols. Similarly, a single antenna or plural antennas may be used on each of the wireless communication devices. Example competing protocols may be local wireless network access protocols such as Wi-Fi, WiGig, and small cell WLAN in an unlicensed, shared communication frequency band. Example communication frequency bands may include unlicensed 5 GHz frequency bands or 3.5 GHz conditional shared communication frequency bands under FCC Part 96. Wi-Fi ISM frequency bands that could be subject to future sharing include 2.4 GHz, 60 GHz, 900 MHz or similar bands as understood by those of skill in the art. Within local portion of wireless network 250 access points for Wi-Fi or WiGig as well as small cell WWAN connectivity may be available in emerging 5G technology. This may create issues with selection of optimal wireless links when concurrent communication on both WLAN and WWAN access may operate within the same communication frequency bands. Such issues may be addressed or mitigated with remedies according to the context aware radio resource management system including a concurrent wireless link optimization system 291 according to embodiments herein.

The voice and packet core network 280 may contain externally accessible computing resources and connect to a remote data center 286. The voice and packet core network 280 may contain multiple intermediate web servers or other locations with accessible data (not shown). The voice and packet core network 280 may also connect to other wireless networks similar to 240 or 250 and additional wireless communication devices such as 210, 220, 230 or similar connected to those additional wireless networks. Connection 282 between the wireless network 240 and remote data center 286 or connection to other additional wireless networks may be via Ethernet or another similar connection to the world-wide-web, a WAN, a LAN, another WLAN, or other network structure. Such a connection 282 may be made via a WLAN access point/Ethernet switch to the external network and be a backhaul connection. The access point may be connected to one or more wireless access points in the WLAN before connecting directly to a wireless communication device or may connect directly to one or more wireless communication devices 210, 220, and 230. Alternatively, wireless communication devices 210, 220, and 230 may connect to the external network via base station locations at service providers such as 260 and 270. These service provider locations may be network connected via backhaul connectivity through the voice and packet core network 280.

Remote data center 286 may include web servers or resources within a cloud environment. For example, remote data centers can include additional information handling systems, data processing servers, network storage devices, local and wide area networks, or other resources as needed or desired. Having such remote capabilities may permit fewer resources to be maintained at the wireless communication devices 210, 220, and 230 allowing streamlining and efficiency within those devices. Similarly, remote data center 286 permits fewer resources to be maintained in other parts of network 200.

In an example embodiment, the cloud or remote data center 286 or networked server 290 may run hosted applications for systems 210, 220, and 230. For example, remote data center 286, networked server 290, or some combination of both may operate some or all of a context aware radio resource management system including a concurrent wireless link optimization system as disclosed in the present disclosure. This may occur by establishing a virtual machine application executing software to manage applications hosted at the remote data center 286 in an example embodiment. Wireless communication devices 210, 220, and 230 are adapted to run one or more applications locally, and to have hosted applications run in association with the local applications at remote data center 286 or networked server 290. For example, wireless communication devices 210, 220, and 230 may operate some or all of the context aware radio resource management system including a concurrent wireless link optimization system software agent in some embodiments. The virtual machine application may serve one or more applications to each of wireless communication device 210, 220, and 230. Thus, as illustrated, systems 210, 220, and 230 may be running applications locally while requesting data objects related to those applications from the remote data center 286 via wireless network. In another example, an electronic mail client application may run locally at system 210. The electronic mail client application may be associated with a host application that represents an electronic mail server. In another example, a data storage client application such as Microsoft Sharepoint may run on system 220. It may be associated with a host application running at remote data center 286 that represents a Sharepoint data storage server. In a further example, a web browser application may be operating at system 230. The web browser application may request web data from a host application that represents a hosted website and associated applications running at remote data center 286.

Although 215, 225, and 235 are shown connecting wireless adapters of wireless communication devices 210, 220, and 230 to wireless networks 240 or 250, actual wireless communication may link through a wireless access point (Wi-Fi or WiGig), through unlicensed WWAN small cell base stations such as in network 240 or though a service provider tower such as that shown with service provider A 260 or service provider B 270 and in network 250. In other aspects, wireless communication devices 210, 220, and 230 may communicate intra-device via 248 when one or more of the wireless communication devices 210, 220, and 230 are set to act as an access point or even potentially a WWAN connection via small cell communication or licensed small cell WWAN connections. For example, one of wireless communication devices 210, 220, and 230 may serve as a Wi-Fi hotspot in an embodiment. Since one aspect of the disclosed embodiments involves assessment and selection of wireless links by a context aware radio resource management system including a concurrent wireless link optimization system using a context aware radio resource management system, no particular wireless link selection is depicted in FIG. 2.

The connection quality of service (QOS) and speed of wireless links 215, 225, and 235 may vary widely depending on several factors including the service provider bandwidth, the number of wireless communication devices and users in a location, and other factors. Quality of service impacts energy consumption and efficiency of a wireless communication device communicating wirelessly. Thus, selection of a wireless link may depend on assessment of the link radio frequency conditions. Assessment of link radio frequency conditions may be made via a context aware radio resource management system and a link rating developed for links. Radio frequency conditions for wireless links will evolve over time. Differences in wireless link QOS or efficiency will also vary minute-by-minute, hourly, daily, weekly or monthly or during even longer periods. Thus, assessment may need to be regular. Wireless intelligence reports may be gathered or crowd sourced in a database accessible by the context aware radio resource management system including the concurrent wireless link optimization system. The wireless intelligence report data base may include wireless link data with respect to wireless link quality of service and experience for a plurality of wireless links at various locations and for particular types of data usage. Additional database information may be available to the context aware radio resource management system including a concurrent wireless link optimization system relating to wireless service usage trends for wireless communication devices such as 210, 220, and 230. These wireless service usage trends may be tracked according to time of day, day of the week, location or other similar factors to indicate how wireless links are used in wireless communication devices such as 210, 220, and 230.

Wireless link conditions will vary depending on the type of service likely to be requested by the mobile information handling system. For example, voice communication may be most efficient on a 2G wireless protocol. Voice communication on 4G and emerging 5G may be more costly in terms of time required for authentication and connectivity negotiation or in terms of transmission power requirements. Data services relating to messaging and SMTP email may have the lowest power cost on 2.5G protocols due to the simplest access barriers there. Higher level data services requiring greater wireless bandwidth may more efficiently use recently implemented protocols. For example, audio streaming may be optimal for 3G protocols. Video streaming and HTTP web browsing may be best suited to 4G protocols or emerging 5G and much less efficient at lower protocols which are not designed to accommodate large data throughput.

As the protocols become more advanced, additional registration and initialization for data becomes costly from a processing and power consumption standpoint. This is balanced against the capabilities of the more advanced protocols to handle data transfers. More complicated communication protocols result in greater processing time and authentication/connection message exchange. More robust processor or controller operation and longer delays for transmitter or receiver circuits consume power. On the other hand, certain protocol advancements are designed to make data transfers quicker and more efficient. Thus for example, the 4G or 5G protocol may generally consume more power during operation than 2.5G for voice communications, but less power for high volume data transfers.

For this reason, the wireless communication device operating context can play an important role in determining wireless link conditions and efficiency from a power consumption standpoint. Information about wireless link connection quality and capacity for a service to be used can be advantageous in optimizing communication channel selection. In most cases, transmission or reception via a macro-cellular network 250 base station at a service provider 260 or 270 will take more power than communication via WLAN such as Wi-Fi. Among macro-cellular systems, energy consumption generally, but not in all circumstances, increases at each advancement of technology protocol from 2G to 5G. Plus, increased traffic levels on an advanced macro-cellular protocol may slow down in comparison to an older technology with less active traffic. Additional future macro-cellular protocols are contemplated as well. Those protocols may require additional energy demands of mobile information handling systems. Additionally, often the QoS of an end-to-end wireless communication path between wireless communication devices of a user and a recipient will most directly be affected the QoS levels at the end stages of the wireless communication path. For example, the wireless link QoS between a user wireless communication device and the wireless network on one end and the wireless link QoS between a recipient wireless communication device on the other end are often the places where communication path quality compromise, capacity limitation, or latency is most likely to occur.

Factors impacting energy consumption include switching and signaling during communication access, setup, and authentication. Additional factors that impact energy consumption include control communications, latencies, transmission/reception, and switching for the wireless link. As described above, these factors can be specific to the type of wireless service being requested, whether voice, messaging, SMTP, Audio, Video, HTTP or other service types. It can also be specific to the wireless communication device used. Certain protocols may not be available on some mobile information handling systems. In each instance, radio frequency transmission subsystems and controllers operate and consume device power. Based on these numerous factors, the system of the present embodiment may automatically switch between radio network technologies or service providers to optimize radio frequency conditions, traffic conditions, device power consumption, cost, or any of the above. Selection of a wireless service provider and technology protocol may generally depend on the optimal wireless technology used for a service requested, the radio frequency conditions of a link, traffic conditions for the wireless link, and availability of a link.

Further, concurrent radiofrequency bands may be used having several channels for wireless link connections and which may include with potential overlapping use of shared radiofrequency bands including unlicensed bands and conditional shared communication frequency bands available under FCC Part 96 with use under Wi-Fi and emerging 5G technologies such as unlicensed small cell wireless links. Accordingly, wireless links 215, 225 and 235 may represent concurrent wireless links for two or more protocols operating within similar frequency bands. With the rise of multiple wireless protocols operating within shared communication frequency bands, wireless links may operate on separate channels within the communication frequency band, including within neighboring channels. In other aspects, the possibility further arises that wireless protocols within a communication frequency band may even attempt to operate on the same channel within a shared communication frequency band. Aspects of the present disclosure may determine potential conflicts within shared communication frequency bands as well as manage or mitigate interference that may arise within such situations.

A context aware radio resource management system with a concurrent wireless link optimization system 291 may assess channels for potential interference and conflict within the shared communication frequency bands. The context aware radio resource management system 291 may maintain RF traffic reports relating to wireless links at a database. That database may be located within the wireless network for example at remote data center 286. RF traffic report database aggregates wireless link QoS data across the wireless network and with respect to wireless communication devices operating with the context aware radio resource management system including a concurrent wireless link optimization system of the present disclosure. The RF traffic report database of the context aware radio resources system maintains performance data of service providers and various wireless protocols available for parts of a wireless communication path. The aggregated RF traffic report database may be accumulated or crowd sourced from multiple wireless communication devices operating on a given network or networks. This feature will be described further below.

Further, the concurrent wireless link optimization system of the context aware radio resource management system 291 may determine or model interference to be experienced by selection of wireless links for multiple protocols, or even for a protocol operating on several channels, that operate simultaneously within a radiofrequency communication band. Wi-Fi/WiGig and small cell WWAN protocols, in an example embodiment, may operate in the same shared communication frequency bands. Data relating to neighborhood interference lists, access point and small cell substation locations, and modeled or measured interference during operation of simultaneous wireless links within a shared communication radiofrequency band are stored by the concurrent wireless link optimization system portion of the context aware radio resource management system 291 in a database, at a remote data center 286, or at individual wireless communication mobile devices 210, 220, or 230. The concurrent wireless link optimization system 291 may determine or alter selection of optimal wireless links based on assessment of potential interference or collision from selection of those wireless links and the channels within the shared band on which they are operating. In other embodiments, the concurrent wireless link optimization system 291 may implement interference or collision mitigation strategies if optimal wireless links are to be selected due to availability, link quality, usage trends, cost, power or other factors taken into consideration by the wider context aware radio resource management system.

FIG. 3 illustrates a wireless neighborhood 310 in an example embodiment. The wireless neighborhood may be a building, campus, shopping area, airport, or other area having a plurality of competing wireless link options available. In some aspects, the wireless neighborhood may be facilities or a campus associated with an enterprise, military, university, government or municipal organization. Within wireless neighborhood 310 there is a plurality of base transceiver systems (BTSs) including several access points (APs) including AP1 320, AP2 325, AP3 330, AP4 335, and AP5 340. As shown, each of the access points may record and report a position including latitude and longitude values. Additionally, in wireless neighborhood 310 is a small cell WWAN substation such as FemtoCell1 315. FemtoCell1 315 additionally may report a latitude and longitude location information. Reports of location may be made to the context aware radio resource management system including a concurrent wireless link optimization system. The concurrent wireless link optimization system may create neighboring interference lists such as 305. Each of the wireless devices are listed in the wireless neighborhood and the type of wireless link supported may be determined. Further, neighboring interference lists 305 may include operating channel frequencies and location of each of the wireless link access options that are either APs or small cell WWAN substations in the present embodiment. Finally, the concurrent wireless link optimization system may establish BTS utilization metrics which may involve estimation of levels or rating of utilization of the APs and the small cell WWAN substations in the neighboring interference lists 305.

FIG. 4 illustrates an example utilization of a shared radiofrequency communication band according to an example embodiment of the present disclosure. In particular, the embodiment of FIG. 4 shows use of the Unlicensed National Information Infrastructure (U-NII) band 405 which typically operates in the ˜5 MHz frequency band such as 802.11 a/h/j/n/ac (e.g., center frequencies between 5.170-5.785 GHz). In this example embodiment, five channels 410, 420, 430, 440, and 450 are shown for illustrative purposes. It is understood that any number of available channels may be available under the 5 GHz shared communication frequency band.

Channel 1 410 represents a device selected channel 418 for WLAN 1 413 (and showing a frequency spectrum across channel 1 410). Similarly, device selected channel 428 for WLAN 5 427 may arise at channel 2 420 in an embodiment which is a neighboring channel to channel 1 410. In another embodiment, device selected channel 428 may also be selected for small cell WWAN 423. Each of WLAN 5 423 and small cell WWAN 427 may be device selected for channel 2 420. In such an example, two wireless links may occupy the same channel raising potential for both interference and collision when operating from the mobile wireless device. This may occur because the wireless links arise under different wireless link protocols operating within the same shared communication frequency band, in this example embodiment the U-NII 5 GHz band.

Device selected channel 438 may arise for WLAN 2 433 on channel 3 430. Device selected channel 448 may arise for WLAN 4 443 on channel 4 440. Device selected channel 458 may arise for WLAN 3 453 on channel 5 450. It is understood that the selection of wireless links for device selected channels by various WLAN options and between protocols is for illustration purposes for an example embodiment of operating on a shared communication frequency band. Any set of channels and selection of wireless links for WLAN or small cell WWAN may arise depending on available BTSs operating as APs and small cell WWAN substations and the channels those devices select to operate on in the wireless neighborhood. Another example of a selection of frequency channels is depicted in FIG. 3 for five APs and a small cell WWAN substation in the neighboring interference list 305 for a wireless neighborhood 310.

FIG. 5 illustrates another example utilization of a shared radiofrequency communication band according to an example embodiment of the present disclosure. In FIG. 5, wireless communication device 501 may communicate according to two protocols, WLAN and small cell unlicensed WWAN, within a shared communication frequency band 505. In the example embodiment, wireless communication device 501 may operate within a shared, unlicensed 5 GHz band 505 via concurrent heterogeneous radios. FIG. 5 further shows an embodiment including a data scheduler according to an embodiment. Wireless communication device may include both a WLAN RF front end wireless transceiver subsystem 512 as well as a WWAN RF front end wireless transceiver subsystem 522 for communication in the shared communication frequency band. For example WLAN RF front end 512 may operate on Wi-Fi wireless radios in an embodiment. In an additional example, WWAN RF front end 522 may operate on unlicensed LTE WWAN wireless radios in another embodiment. Many wireless communication device 501 sold include only wireless communication system available with unlicensed wireless radio frequency communication capabilities. These devices may be referred to as standalone devices. In other aspects not described in detail with the present embodiment of FIG. 5, wireless communication devices such as 501 may further include wireless transceiver systems capable of transmitting with licensed wireless communication bands via a service provider such as under the 2.5G to 5G protocols discussed above.

In the present example embodiment, wireless communication device 501 may include a shared antenna 560 for both WLAN/Wi-Fi as well as WWAN small cell unlicensed communications within the shared communication frequency band 505. In other embodiments, separate antenna systems may be utilized for transmission on different protocols but may not be necessarily arranged this way. Wireless communication device 501 may communicate with a source of data 518 such as a CPU or other processor or controller via one or more busses 510 and 520 to obtain device data for transmission along any of the plurality of wireless link protocols. Device data source 518 may include a master transmission queue, such as a buffer memory or other memory, at the CPU or other processor. For example, data may be transmitted via a wireless link 561 on a WLAN protocol such as Wi-Fi. Data may also be transmitted on wireless link 562 using a small cell unlicensed WWAN protocol. In an example embodiment, selection of wireless link routes may be made in a smart connection context. Wireless links 561 and 562 may operate in the shared communication frequency band 505. Data for transmission from a data source 518 to wireless communication device 501 may be transmitted via a shared antenna 560 or via separate antennas for each protocol as described.

In one aspect of the present embodiment, the wireless communication device 501 may transmit data via a data scheduler system. In the event of transmission via a WLAN wireless protocol front end 512 and a small cell WWAN wireless protocol front end 522 via a shared antenna 560 in a shared unlicensed communication band 505, data queues for each wireless communication protocol may be used. A WLAN/Wi-Fi queue 514 is shown in FIG. 5 and may be used to schedule data on the shared communication radiofrequency band 505 concurrently used with the small cell WWAN protocol by the wireless communication device 501 in an embodiment. Similarly, a small cell WWAN queue 524 is shown in FIG. 5 and may be used to schedule data on the shared communication radiofrequency band 505 concurrently used with the WLAN/Wi-Fi protocol by the wireless communication device 501 in another aspect of the present embodiments. WLAN/Wi-Fi queue 514 and small cell WWAN queue 524 may be used as a data scheduler for data scheduling for transmissions from the wireless communication device 501 in the shared, unlicensed communication band in some embodiments as described further herein. Data queues 514 and 524 may be a memory such as a buffer memory or other type of memory storage device for temporary storage of data to be transmitted across wireless links 561 and 562. In an example embodiment, data queue memory may include available RAM, such as DRAM, or solid state memory, or another fast response memory for purposes of data scheduling

As described, a data scheduler may be used to prevent collisions if the two protocols of WLAN and small cell WWAN used by the wireless communication device 501 operate on the same channel or to reduce interference if the two protocols concurrently operate on adjacent channels. Data scheduling may utilize transmission timing to allow transmission across a same channel wireless link or adjacent channel wireless links concurrently, but may avoid simultaneous transmission which would create collision or interference. Round-robin, modified round-robin, or data prioritization scheduling may be used between the concurrently operating wireless link protocols as described in example embodiments herein.

In another aspect of the present embodiment, the wireless communication device 501 may receive data instead of transmit data. In an embodiment of FIG. 5, remote data sources such as BTSs may utilize a data transmission queue for the purposes of data transmission scheduling as a way of regulating received data within the shared communication frequency band 505. This may be especially useful to remediate interference caused by use of a shared antenna or proximate antennas in the wireless communication device 501 for the two available wireless link protocols. For example, available wireless link protocols for concurrent operation may include WLAN and small cell WWAN.

Data may be stored in queue at the remote data sources or at BTSs transmitting data and scheduled depending on whether active transmission is occurring on the same channel or an adjacent channel within the shared communication frequency band 505. In the case of same channel usage by the two protocols, data scheduling from a remote data source or a BTS transmitting on a shared communication frequency band 505 may remediate collision. In the case of adjacent channel usage by the two available protocols, data scheduling at one or both data sources may mitigate interference during simultaneous reception along the two active protocols, such as the WLAN and the small cell WWAN, for the wireless communication device 501. In an aspect, a remote data source may utilize a control channel connection to determine from among a plurality of wireless protocols to transmit data along wireless links, for example 561 and 562, from the remote data source or sources thus potentially increasing bandwidth to wireless communication device 501.

FIG. 6 shows a context aware radio resource management system including a concurrent wireless link optimization system for connection by a user wireless communication device via an optimized wireless communication path according to an embodiment of the present disclosure. The context aware radio resource management system including a concurrent wireless link optimization system may be implemented in connection with a context aware radio resource management used in selecting a network and technology within a wireless network for a given location. In some example embodiments, the concurrent wireless link optimization system may be used to eliminate wireless links (e.g., wireless link pairs in concurrent operation) or to adjust down the ranking of wireless links likely subject to high interference or collision for consideration by the context aware radio resource management system during selecting one or more optimal wireless links.

In one example embodiment, the context aware radio resource management system may determine a selection or list of optimized wireless link options in a wireless neighborhood before the concurrent wireless link optimization system portion will determine local interference between concurrent wireless link pairs. In another example embodiment, the concurrent wireless link optimization system portion will determine local interference between concurrent wireless link pairs before assessing a list of optimized wireless links for communication via the remaining operation of the context aware radio resource management system. It can be appreciated as well that determination of potential interference of concurrent wireless links at a user wireless communication device may also be assessed simultaneously with other factors of the context aware radio resource management system in affecting rankings of available wireless links in the wireless neighborhood.

In a particular embodiment, the concurrent wireless link optimization system may determine interference or same channels operation of two or more WLAN or small cell WWAN protocols in a wireless neighborhood. The concurrent wireless link optimization system of the context aware radio resource management system may further determine what to do about a determined high level of interference or potential for collision. In one embodiment, the concurrent wireless link optimization system may opt to bar selection of same channel concurrent wireless link operation or adjacent channel concurrent wireless link operation from user wireless communication device. In other aspects, the concurrent wireless link optimization system may opt to switch to a different channel given sufficiently good wireless quality and other factors for selecting a different channel. In yet another aspect, the concurrent wireless link optimization system may allow same channel or adjacent channel concurrent wireless link operation but implement interference or collision mitigation to reduce the effects of anticipated interference.

As described, the context aware radio resource management system of the present disclosure may utilize crowdsourced feedback on QoS for wireless network connections or various links within the networks. FIG. 6 shows an example embodiment of operation of the context aware radio resource management system including a concurrent wireless link optimization system in determining an optimized list of available wireless links. An example context aware radio resource management system is disclosed in several patent applications and issued patents of the same assignee. Additionally, factors and wireless network data relating to the context aware radio resource management system may be utilized by the context aware radio resource management system including a concurrent wireless link optimization system in providing end-to-end scores and selection of preferred wireless communication devices and preferred wireless communication paths between those preferred devices for a user and/or a recipient. Selection of two or more optimized wireless links for concurrent operation may be automatically by the context aware radio resource management system including a concurrent wireless link optimization system in some embodiments. In an embodiment, the selection by the context aware radio resource management system including a concurrent wireless link optimization system may be made with an override option available to a user. In yet another embodiment, the context aware radio resource management system including a concurrent wireless link optimization system may present an advisory graphical user interface including wireless link quality ratings to provide a user an informed choice of concurrent wireless links. Alternatively, the context aware radio resource management system including concurrent wireless link optimization may assist in selection among optimal wireless communication devices and an optimal wireless communication path via concurrent wireless links for a communication type by a user mobile information handling system.

Several factors are assessed by the context aware radio resource management system including a concurrent wireless link optimization system and its coordination with a context aware radio resource management method in selecting a radio technology for a wireless communication path and wireless communication devices for a user and/or recipient. A software agent may be deployed at a wireless communication device or elsewhere in the network for executing the context aware radio resource management system including a concurrent wireless link optimization system and aspects of the context aware radio resource management system.

The context aware radio resource management system including a concurrent wireless link optimization system may further utilize the software agent to access wireless communication device usage trend data 610. The context aware radio resource management system including a concurrent wireless link optimization system may detect and learn patterns of usage by an individual user or recipient for particular wireless communication types. In an example embodiment, a usage preference score may be assigned to each as a percentage of time spent utilizing a particular wireless communication type or as a percentage of instances of using a particular wireless communication type. This data may be stored for a user or recipient in a wireless communication device usage trend database and shared across an enterprise or group via a context aware radio resource management system including a concurrent wireless link optimization system manager in certain aspects. In an example embodiment, wireless communication device usage trend data for a user or recipient is shown below in Table 1. The data may be relevant to a particular time of day during which wireless access is sought.

TABLE 1 Usage preference Communication Type User Device score SMS Text User A Smart Phone 20% Video conference User A Smart Phone  5% Voice call User A Smart Phone 30% IM User A Smart Phone 15% Web/App data User A Smart Phone 30% SMS Text User B Notebook  0% Video conference User B Notebook 15% Voice call User B Notebook 10% IM User B Notebook 20% Web/App data User B Notebook 65% SMS Text User C Tablet  0% Voice call User C Tablet 10% Video conference User C Tablet 20% IM User C Tablet 20% Web/App data User C Tablet 50%

It is understood that the wireless communication device usage trend data may vary widely depending on data collection of a user's trends. The wireless communication device usage trend data may begin with certain default levels and be adjusted over time as usage data is collected for wireless communication types. It is noted that in the above example embodiment the usage preference scores sum to 100% for each wireless communication device type and user. The listing of data communication types may be further granulated in some embodiments and the above is a generalized example of user trend data gathered by data communication types. For each communication type event, the time or number of instances of the communication type with a wireless communication device is divided into total time or number of instances of all communication types for a user in the example embodiment. The above values are example data meant for the purposes of illustration. Further, this data may be specific to time of day or location and be available in spatial-temporal profiles of a user or of a mobile information handling system. Additional criteria may be implemented and may alter the scoring from adding to 100% depending on the scoring system used in other embodiments as is understood by those of skill.

The usage preference score may serve as a weighting factor for usage rating that may impact which wireless link quality ratings are used to determine an optimized list of wireless links or wireless communication paths and selection of preferred wireless links for devices for a user, a recipient, or both. The usage preference score is associated with the wireless communication device and communication type. An additional factor that may be added to the usage preference score is cost. In an embodiment, use of technologies with extremely low cost such as unlicensed communication band wireless links including Wi-Fi, small cell WWAN, or peer to peer protocols such as Wi-Fi Direct or Bluetooth Peer-to-Peer as a communication paths may increase usage preference scores due to low cost. Cost may also be considered as part of the wider list ranking of optimized wireless links available for the wireless communication devices. In an example embodiment, a low cost option may shift a usage preference score by 50% in an example embodiment if the wireless link QoS is sufficient. Any shift amount is contemplated in the settings of a context aware radio resource management system however. Other example alterations to usage preference scores are contemplated as well including preferences expressed via a user interface by a user or recipient for a particular wireless communication link or path. These may shift the usage preference score of one or more available wireless communication devices. The shift of preference may be by any amount. In one example embodiment, the expressed preference may shift the usage preference score for that wireless communication device by up to 50%. As understood, any shift in preference percentage or assigned weighting factor may be applied in the design of the context aware radio resource management system in various embodiments.

In another example embodiment, the context aware radio resource management system software agent obtains other user profile data that may also be utilized by the context aware radio resource management system including a concurrent wireless link optimization system that may shift usage preference scores for wireless communication devices. Such user profile data may be included with the wireless communication device usage trend data 610 and may be used in connection with the context aware radio resource management system including a concurrent wireless link optimization system for tracking user trends for wireless communication types. In an example embodiment, the user profile data from the context aware radio resource management system may establish an approximate cyclostationary usage pattern of each wireless communication device on a daily or weekly basis. The time of day, location, types of usage, and usage percentages during a sample time interval are example factors included in the user profile data. This user profile data also may include a confidence of the estimate. This may be a statistical measurement of a mean and standard deviation for a set of data. Alternatively, the confidence of estimate may involve a goodness of fit metric to an expected set of values. Alternative statistical analysis may be performed on the user profile data to provide a confidence of the estimate. These cyclostationary usage patterns may used to shift weighting the usage preference scores in view of anticipated usage or future availability of wireless communication devices based on time of day and location or predicted location in a wireless neighborhood as described. The shifting of usage preference scores may be by any amount depending on several factors. Cost, expressed preference for wireless link, and other factors may shift user profile data that contributes to device usage trend data.

The context aware radio resource management system including a concurrent wireless link optimization system may also receive wireless link radio frequency broadband traffic reports 620 and may be in accordance with time and location data for a user or recipient and their associated wireless communication devices. In an example embodiment, the wireless link radio frequency broadband traffic reports 620 may be retrieved from the context aware radio resource management system. For location and time, available radio technologies and, where relevant, available service providers may be listed for a wireless communication neighborhood. The reports contain data relating to location, time and a radio frequency profile of given radio technologies for the available service providers. Certain radio technologies, such as those subject to concurrent wireless link operation, may not specifically be associated with a service provider such as in the case of Wi-Fi/WLAN, small cell WWAN, or similar wireless network connection options. These concurrent wireless links operate in unlicensed, shared spectrum as described. The radio frequency profile data may also include an associated confidence of estimate for link ratings or QoS scores. The wireless link radio frequency profile may combine recent reports, historical traffic reports, as well as data measured via an active device radio frequency scan. In an example embodiment, to minimize wireless communication device battery power consumed, radio frequency broadband traffic reports from the network may only be requested or sent when a service provider network or a wireless communication device detects a significant change in signal quality or the network broker server detects that the local crowd source information is out of date.

The wireless link radio frequency broadband traffic report for wireless links partially comprises a spatial-temporal radio frequency profile for the wireless links. The systems begins with a baseline report available from a context aware radio resource management system. The context aware radio resource management system may determine QoS metrics for various wireless links from crowd sourced data received from a plurality of wireless communication device operating within a wireless neighborhood. Data may include several factors of wireless QoS measured or sourced to the context aware radio resource management system.

Key performance indicators (KPI) comprise a spatial-temporal radio frequency profile. Data such as received signal strength (RSSI), signal-to-noise ratios (SNR), or signal to interference ratios (SIR) may be relevant channel quality indicators in a KPI matrix. Other data, may include data throughput speeds, communication latencies, jitter, and packet loss measurements. The context aware radio resource management system may actively assess the quality of wireless links being used. One or more of these performance indicators may be used to compute a link rating for a wireless link. Baseline reports rely on estimated values. For example using baseline estimated received signal strength indicators (RSSI), a link rating may be computed as follows in one embodiment:

Link Rating (i, j)=MAX (MIN (100%, (Estimated RSSI−Minimum Signal)/Max RSSI signal−Minimum RSSI signal, 0%), where i is a technology index and j is a wireless protocol index.

A maximum RSSI level may be defined in a technology protocol, for example as −70 dBm. The minimum RSSI level may be defined as well, for example at −110 dBm. RSSI is not the only key performance indicator that may be used to compute link ratings. Link rating may be based on different key performance indicator values besides received signal strength. Alternatively, multiple key performance indicator values may be used in the computation of a link rating.

In other examples of KPIs that may be used for link rating, link capacity and bit error rates (BER) may be measured. Bit error rate is the ratio of error bits to total bits sent across a wireless link. It is a metric illustrating a signal to noise ratio which can define the quality of a radio connection for a wireless link. A bit error rate may be a comparison of a sent test stream of data by a transmitter with what is received by a receiver. The bit error rate can be tested by a bit error rate tester in software which transmits a known bit pattern to or from the mobile information handling system. Pre-error correction errors are counted. A signal-to-interference ratio may also be measured. Such a measurement is based on the power levels for signal transmission (e.g., per bit) relative to interference levels in the received signal. Packet error rate, signal-to-noise measurement, or other signal quality testing is also contemplated. Data packets, such as test packets or active data, may be monitored as it is sent across wireless links to determine packet loss frequencies or resend occurrences for the packets.

A link rating matrix is established by available link protocols and may be broken down by wireless technology, service provider, or both. In an example embodiment, for a matrix of [WLAN 2, WLAN 3, Small Cell WWAN, WWAN 4, ATT 4G, Verizon 4G], the baseline Link Rating (j) computation may result in (70%, 80%, 95%, 90%, 50%, 50%). 100% indicates best signal link quality and 0% indicates a signal quality below a minimum acceptable level. The context aware radio resource management system may use the link rating scores to evaluate the optimal wireless service providers and available protocols for the anticipated usages for a wireless link that comprises a portion of an end-to-end wireless communication path. Thus, the link rating protocol matrix can assist in selecting wireless links and a service provider with the best scores.

The context aware radio resource management system operating on a wireless communication device may scan for wireless link mobile broadband traffic reports fitting a time and location zone for operation. In an example embodiment, the zone of operation may be a wireless neighborhood as described above. Wireless link mobile broadband traffic reports may be retrieved from a central server database in the wireless networks. Alternatively they may be located elsewhere in a database such as at a network broker server system. The baseline report may be supplemented or superseded by any fresh or historical mobile traffic reports to assist in selecting a service provider and protocol. Recent or historic radio frequency profiles for time period and location zone may be used to update or supplement the wireless link mobile broadband traffic reports. More recent data may be of greater relevance however. For example, the link ratings in a radio frequency profile may utilize recently measured RSSI values instead of estimated values.

Mobile broadband traffic reports are aggregated via crowd sourcing. They may be categorized by location zone and have time and date stamps to identify freshness. Crowd sourcing of information will enhance the availability of accurate data for location zones and times of wireless communication device operation. For example, if a wireless communication device makes a request for a fresh mobile broadband traffic report, the central server database may have reports from other wireless communication devices with recent timestamps. Alternatively, the central server database may make a request for a recent mobile broadband traffic report from wireless communication devices in the same location. Whether via recent storage in the central database or via a recent request of fresh crowd sourced mobile broadband traffic reports, such a report may avoid the need for the wireless communication device to conduct a radio frequency scan itself.

Crowd sourcing mobile broadband traffic reports for locations and times provides a higher chance that a current mobile broadband traffic report for a location is available. It also increases the available data points providing greater certainty and reliability of data. Part of the benefit of crowd sourcing may also involve performing a hysteresis analysis on the data coming from multiple wireless communication devices to determine trends in wireless link selection. When a wireless link is reported having low traffic and good radio frequency conditions, traffic from systems using the context aware radio resource management system will elect that wireless link. If a large part of the crowd of wireless communication devices begin to pile onto whichever wireless link is reported to have the best available bandwidth, that link will slow down and underperform. The mobile broadband traffic reports account for this by conducting a hysteresis analysis. If a large number of users begin to select this wireless link, then the method for generating mobile broadband traffic reports accounts for this traffic and alters the recommended wireless links. For example, a second best option may be recommended as optimal for traffic and radio frequency conditions instead. Each crowd sourced mobile broadband traffic report identifies its selected link. A count of these selections can be compared to a threshold rate level of selections for a given link. If the rate of selections exceeds the threshold for a link, then the recommendation may be altered.

If there are not enough reliable historical mobile broadband traffic reports recent enough to base a wireless link assessment upon, the context aware radio resource management system may initiate a wireless communication device radio frequency scan. This scan collects data regarding possible wireless links. This radio frequency scan consumes power and processor resources so should be used sparingly, however it provides up-to-date key performance indicators (KPI) for a new radio frequency profile to be used in a mobile broadband traffic report. Based upon this new mobile broadband traffic report, the system provides a wireless link performance profile to be used by the context aware radio resource management system.

The scan or test of radio frequency links may be conducted by the context aware radio resource management system. As a first measure, received signal strength and bandwidth availability for a service provider and a protocol are determined. Then a test of radio frequency data capacity is made. This can test upload and download performance for each service provider and protocol. For example, a standard test data volume may be sent via a wireless link to a server location at the service provider. Similarly, a test data volume may be received from a server location by the wireless communication device via the wireless link. Latency of response, upload and download speed or throughput can then be measured for the service provider and protocol. The data is associated with a location zone and stamped with a time and date. The type of transmitter/receiver or wireless communication device may also be recorded. This data set provides a wireless link radio frequency profile that may become part of a mobile broadband traffic report. Upon measuring this data for a location, the report may be shared or published by the context aware radio resource management system from the mobile information handling system.

In one embodiment, the wireless link assessment may be used by the context aware radio resource management system including a concurrent wireless link optimization system to determine a ranked list of wireless communication links available within a wireless neighborhood. Further assessment may include determining a ranked list of available wireless communication links for communication along a wireless communication path between two points across the wireless communication network, including various steps or hops across links within the wireless communication network. Using user profile reports and radio frequency link reports, each wireless communication link may be given an overall rank.

For a ranking of wireless communication path end-to-end, several methods may be used to determine wireless communication path overall quality score or. In one example embodiment, it may be assumed the wireless communication path is only as good as the lowest link rating score along that path. Thus, the wireless communication path rating may be determined as the same as the minimum link rating in the communication path. In another embodiment, the wireless communication path rating may take into account the diminished quality of each wireless link in the communication path that is rated at less than 100%, or a perfect rating for a link. Thus a calculation whereby the effect of each wireless link rating less than 100% determines some diminishment on the overall wireless communication path rating. In an example embodiment, the wireless communication path rating may be determined as a product of a wireless link rating of the connecting link for the user wireless communication device with the wireless link rating of the connecting link for the recipient wireless communication device as follows:

Wireless Communication Path Rating (j)=(Link Rating for Link from Wireless Device A*Link Rating for Link from Wireless Device B), where j=communication path index.

For a wireless communication path=[AT&T® 3G for Device A, Verizon® 4G for Device B], an example user Wireless Communication Path Rating (j) calculation may result as follows, (90%*70%)=63%. Each wireless communication path for a user wireless communication device and a recipient can be ranked by this score. Each Link Rating used to determine the Wireless Communication Path Rating shows a quality of service score by protocol for a service provider at a location and time. For a given communication path, the Wireless Communication Path Rating may serve as an initial end-to-end quality rating upon which selection of a wireless communication path may be made by the pan device communication optimization system. The Wireless Communication Path Rating may also include additional wireless links and Link Ratings for those links along the path. Additional weighting factors may apply to the initial end-to-end quality rating to yield modified end-to-end ratings for wireless communication links for selection of wireless communication paths and user and recipient wireless communication devices. This is described further below. The above values serve only as an example for purposes of discussion.

In another aspect, energy link reports 640 may be received as a variation of the wireless link radio frequency broadband traffic reports 620. These energy link reports 640 contain data relating to time, location and radio frequency profile information similar to the radio frequency broadband traffic reports. In addition, measurements of energy consumed during use of a specified wireless link for a specified wireless service type is reported. The energy link data profile matrix can provide more detailed information above the mobile broadband radio frequency traffic reports. In this embodiment, the context aware radio resource management system prepares and delivers an energy link consumption report. The energy link consumption report provides data on power consumed by a wireless communication device while performing certain tasks on a wireless link at a location. Energy link consumption reports contain data indicating how many joules of energy are consumed during sending SMTP emails, sending SMS messages, conducting voice communications, video conferencing, IM, accessing internet services, streaming audio or video, or other uses of mobile information handling systems. This data amounts to another key performance indicator (KPI) in addition to capacity or link quality data for a wireless link. The context aware radio resource management system can measure and utilize some or all data such as link capacity, link quality, and energy consumption in determining preferred wireless links. Link ratings may be calculated similarly to the above description using the additional link energy consumption data. As with other input factors, a confidence of estimate associated with this data may be included. The energy link report data 640 may combine recent energy link profiles, historical energy link reports, and measurements through wireless communication device scans during operation.

The context aware radio resource management system including a concurrent wireless link optimization system may access battery power level data 630 for user wireless communication devices. In an example embodiment, the context aware radio resource management system including a concurrent wireless link optimization system may access the battery power level data 630 via the context aware radio resource management system which receives battery power level data from an intelligent battery management system of the wireless communication devices in the system. The battery power level input may establish thresholds for certain wireless communication protocols as being too costly in terms of power based on the remaining battery power available. Below a defined battery level threshold, the context aware radio resource management system may disable the most advanced protocols to save energy. For example, with only 10% battery power remaining, the context aware system may recommend to a user to disable high power consuming protocols such as 4G. The option may be given to the user, or automatic shut down of the radio frequency subsystem may take place. In a further example, the context aware system may recommend or shut down 3.5G at 5% remaining battery power. Any threshold levels may be set to trigger recommended shut down. In such a shut down, that wireless link rating will be at 0% or disconnected and impact the communication path overall ratings and the wireless communication device rating by the context aware radio resource management system including a concurrent wireless link optimization system of the present disclosure.

In another embodiment, the battery power level data 630 may also be implemented directly by the context aware radio resource management system including a concurrent wireless link optimization system as another factor in consideration of end-to-end scores for wireless communication paths and for user or recipient wireless communication devices. For example, if a user wireless communication device such as a mobile smart phone is at a battery power level below a certain threshold, this may reduce the end-to-end scores for wireless communication paths involving that user wireless communication device. This is especially true for certain wireless communication types such as video conferencing or voice calls. In an example embodiment, the context aware radio resource management system including a concurrent wireless link optimization system may include battery power levels for available wireless communication devices associated with users or recipients as a power weight score for the wireless communication devices and associated links in the communication path. The power weight score for each wireless communication device weights the link ratings for those devices and modifies the initial end-to-end score determination for wireless communication paths involving the wireless communication devices with battery power level data available.

The context aware radio resource management system including a concurrent wireless link optimization system accesses the wireless communication device usage trend data 610 and receives the wireless link radio frequency broadband traffic reports 620, battery power level data 630, and in some energy link reports 640.

Turning to 650, the context aware radio resource management system including a concurrent wireless link optimization system determines wireless communication link scores for available wireless links within the wireless neighborhood. In some embodiments, end-to-end scores for available wireless communication paths between available user wireless communication devices and available recipient wireless communication devices are generated at 650. The context aware radio resource management system including a concurrent wireless link optimization system may determine a list of ranked wireless links available within a wireless neighborhood in some embodiments. In other embodiments, the context aware radio resource management system including a concurrent wireless link optimization system may establish a plurality of available wireless links that meet a minimum sufficient level of criteria of QoS, power consumption, cost, or other factors in view of contextual usage of the wireless communication device.

The above data and inputs may be assessed by the context aware radio resource management system including a concurrent wireless link optimization system determine one or more preferred wireless communication links for a user wireless communication device at 650. In an example embodiment, one or more optimized wireless links may be determined at for a mobile information handling system in one or more unlicensed communication frequency bands, such as for a standalone device. In a further aspect, a plurality of wireless link options are determined for concurrent operation to enable greater communication bandwidth and reliability. In some embodiments, the plurality of optimized wireless links best suited for a data usage may be concurrently operating wireless links in an unlicensed, shared communication frequency band.

In one aspect, the above data and inputs are assessed by the context aware radio resource management system including a concurrent wireless link optimization system determine one or more preferred wireless communication end-to-end paths for a user wireless communication device at 650. In an example embodiment, the end-to-end rating for wireless communication paths begins by selection of a user wireless communication device (Device A) and a recipient wireless communication device (Device B). Scanning assessment is made of available wireless communication options for communication between Device A and Device B. If a low cost connection such as Bluetooth Peer to Peer, WLAN, Small Cell WWAN, or Wi-Fi Direct options are available and have sufficient capacity and signal quality, such a selection may be made. However, such wireless connections may also be included in the context aware radio resource management system including a concurrent wireless link optimization system assessment of all end-to-end communication paths with multiple wireless path links. Assessment of communication paths between user wireless communication device (Device A) and a recipient wireless communication device (Device B) will include additional available network path options on various communication technologies and may include concurrently operating wireless links for use in shared communication frequency bands. The context aware radio resource management system including a concurrent wireless link optimization system estimates an end-to-end link quality score for each wireless connection path between Device A and Device B as described above. In an example embodiment, the context aware radio resource management system including a concurrent wireless link optimization system may access the context aware radio resource management system to determine the wireless Link Ratings from Device A to an available network and Link Ratings from a back-end wireless network to Device B. Link Ratings may also be determined for any number of intermediate hops or links along the wireless communication path being assessed. The Link Ratings may be determined from wireless link radio frequency broadband traffic reports 620 as discussed above. An end-to-end quality score is estimated from the above Link Ratings for one or more alternative service providers and technologies for wireless communication paths between Device A and Device B. Additionally, the end-to-end quality scores for wireless communication paths are similarly estimated between one or more user wireless communication devices and one or more recipient wireless communication devices. An aggregation of end-to-end quality scores involving a user wireless communication device may indicate an initial assessment of a preferred user wireless communication device before usage trends for communication types are assessed. For example, the Link Rating for wireless link connection between Device A and a wireless network technology may be combined with the Link Rating for the connection between Device B and the same or different wireless technology that form the end-to-end wireless communication path between Device A and Device B. For wireless communication paths with multiple wireless hops or links, the product of the plurality of the Link Ratings may be used to arrive at an initial end-to-end quality score for the end-to-end wireless communication path. In another embodiment, the lowest Link Rating of among the wireless links in the end-to-end wireless communication path may be adopted as the end-to-end quality score. It is understood that the wireless communication path may span across multiple service providers or wireless technologies.

Similarly, preferred recipient wireless communication devices may be initially assessed as preferred based on estimated end-to-end quality scores associated with that wireless communication device. As is discussed further, the initial end-to-end estimated quality scores are modified by battery power data and by user preference data to yield final end-to-end ratings. Other modifications to end-to-end ratings may also be implemented. The context aware radio resource management system including a concurrent wireless link optimization system may present an advisory graphical user interface including final end-to-end quality ratings to provide a user an informed choice of optimal wireless communication devices and an optimal wireless communication path for communication via a communication type between a user and a recipient as explained. The end-to-end quality ratings may include the final end-to-end scores or scores for individual wireless devices and may appear similar to that shown in Table 2. In other embodiments, the advisory graphical user interface including end-to-end quality ratings may include a more qualitative rating for wireless devices, providers, or technologies for wireless communication paths between a user and a recipient. In an example embodiment, an end-to-end quality rating such as “good,” “better,” or “best” may be used. Each qualitative end-to-end rating may be assigned a end-to-end quality score range in an example implementation. It is understood that other qualitative indicators are also contemplated for use with the an advisory graphical user interface including final end-to-end quality ratings.

In an example embodiment, battery power levels 630 for wireless communication devices may be applied to initial end-to-end quality estimations to yield updated end-to-end quality rating for wireless communication paths. Such a battery power level may be applied as a multiplier weighting factor to the initial end-to-end quality estimations. In an embodiment, the new adjusted end-to-end score=Initial end-to-end quality estimation*Power weight score (Device A)*Power weight score (Device B). The power weighting score is assigned as a percentage. For example, above a threshold battery power level for a device (e.g., 40%), the power weight score may be set at 100%. Below the threshold battery power level, the power weight score decreases to 0% for a device power level at a second lower threshold power level (e.g., 5%). It is understood that any threshold levels may be used in establishing the power weighting score index with reported battery power levels for the wireless communication device. In a further example, the power weight score of 100% may be assigned for device power levels above 50% battery capacity remaining. The power weight score index line may linearly drop 100% to zero for device power levels between 50% and 10%. It is understood that any power weight score index curve relating to the device power level may be applied. Further, for a wireless communication path involving multiple hops and devices, a power weight score may be applied for each device along the wireless communication path if applicable.

In yet another embodiment, the battery power levels and user usage preference scores may be applied to alter the initial end-to-end quality estimation scores. In an example embodiment, the new adjusted end-to-end score=Initial end-to-end quality estimation*Usage preference score (Device A, Communication type, Cost)*Power weight score (Device A)*Usage preference score (Device A, Communication type, Cost)*Power weight score (Device B).

The assessments and link rating determinations described above for end-to-end quality estimation scores may be applied on one side only, for example for Device A or Device B only. In such an example embodiment, the context aware radio resource management system may determine link ratings for a mobile information handling system in a wireless neighborhood, such as Device A on one side only. It is understood that the wireless link rating assessments with respect to only one device, such as Device A, may yield a list of wireless link ratings for that mobile information handling system according to embodiments herein. In some aspects, data for a recipient wireless communication device, such as Device B, may not be relevant if data is accessed on a server or other hardwired network device. In other aspects, data for a recipient device may not be available or implementation of assessment of the entire end-to-end path including the recipient device may not be desired. In such example embodiments, an assessment may be made according to the above examples for wireless links relating to a single mobile information handling system and rated according to the portion of the descriptions above relating to only one mobile information handling system.

Proceeding to 655, the context aware radio resource management system including a concurrent wireless link optimization system will assess the available optimized wireless link options for local interference. In an embodiment, the wireless communication device may concurrently operate two or more wireless links to increase bandwidth or for additional wireless link availability. As described herein, concurrent operation of two or more wireless links may arise in shared radiofrequency communication bands. For example, concurrent wireless links may operate in the unlicensed U-NII band which may be shared by WLAN/Wi-Fi and emerging 5G small cell WWAN systems. With competing wireless link protocols operating concurrently on shared communication frequency bands, interference may arise due to BTS transceivers operating on the same channels or adjacent channels within these shared communication frequency bands. For example, wireless neighborhoods such as depicted in FIG. 3 may be set up without particular determination of channels that each BTS transceiver operates on. Thus, a wireless communication device communicating concurrently with multiple transceivers, from a shared antenna in some embodiments, may encounter interference from operating on adjacent channels or even the same channel within the shared communication frequency band. The context aware radio resource management system includes a concurrent wireless link optimization system to determine if available wireless link pairs may be such that they would concurrently operate on adjacent or even the same channel. The concurrent wireless link optimization system will receive data relating to neighboring interference lists for various available concurrent wireless links.

Other aspects of interference may be assessed as well at 655. In addition to interference at a mobile information handling system due to concurrent wireless links operating there, interference may be experienced at BTSs in the wireless neighborhood. Interference at the BTSs includes interference from other APs and small cell transceiver substations. BTS interference may occur due to deployment of several protocols within a shared communication frequency band. BTS interference may further depend in part on proximity of BTS devices transmitting within a shared communication frequency band. Assessment of this interference may be determined or modeled and impact the selection of concurrent wireless links operating if operating within a shared communication frequency band. In an example embodiment, total risk of interference or collisions due to concurrently operating wireless links may be assessed at the mobile information handling system as well as at the selected BTSs at 655 to determine or optimize concurrent wireless links.

Based on the channels occupied by potential wireless links pairs, an assessment may be made of collision or interference potential. The interference may be based on modeled interference from adjacent channel operation or may be measured by the concurrent wireless link optimization system through the network interface subsystem. In response to determination of potential significant interference or risk of collision, some concurrent wireless link pairs may be eliminated from consideration among a list of ranked wireless links available within a wireless neighborhood in some embodiments that meet a minimum sufficient level of criteria of QoS, power consumption, cost, or other factors in view of contextual usage of the wireless communication device. In other embodiments, the concurrent wireless link optimization system may impact the ranking of potential concurrent wireless pairs from the determined risk of collision risk or interference due to concurrent operation at a wireless communication device.

In yet another aspect, which may be encountered within the context of a wireless communication device that is a standalone device with limited wireless communication options, the context aware radio resource management system may determine to not concurrently operate transceivers, for example, to entirely avoid data collision. For example, a standalone information handling system may not have service provider wireless service options and be left with options to communicate via one or more shared communication frequency bands. In such a situation, risk or collision or significant interference may result in an election not to operate concurrent wireless links or to prohibit selection of a pair of concurrent wireless links that operate on the same channel.

As yet another aspect, the concurrent wireless link optimization system may deploy interference or collision remediation to minimize or avoid potential collision or interference for a selected pair of wireless links. For example, interference mitigation may include applying adaptive band-pass filtering or data transceiver scheduling for concurrently operating pairs of wireless links that may operate on the same or adjacent channels in the same frequency band.

At 660, the context aware radio resource management system including a concurrent wireless link optimization system selects one or more preferred wireless communication links or paths based on comparison of the optimized wireless link rating scores including adjustments made due to the interference or collision assessment made via the concurrent wireless link optimization system. The context aware radio resource management system including a concurrent wireless link optimization system assesses usage trends, interference of concurrently operating protocols on shared communication frequency bands, RF traffic reports, battery power levels, energy link reports, and additional factors, such as subscriber cost of wireless link usage, to establish wireless link or end-to-end wireless path ratings for the wireless communication device. As with other factors, subscriber cost or settings may influence the determination by weighting protocol options and influence the scoring described above. In an example embodiment, it may be used as a multiplier or other weighting factor in determining end-to-end ratings or scores for wireless communication paths. Alternatively, settings or subscriber cost may be used to mask out protocol options altogether. For example, cost or battery energy power levels may mask out protocol options or wireless communication devices in some embodiments. Due to these factors of cost as well as power consumption, in may arise that a plurality of wireless links may be selected from the available WLAN and small-cell WWAN options in a wireless neighborhood. In some embodiments, these WLAN and small cell WWAN links are often available at no cost, and their close proximity yields lower connection requirements and transmission power costs. Based on one or more of the above-outlined aspects, the context aware radio resource management system including a concurrent wireless link optimization system selects a plurality of available wireless links while avoiding local interference or implementing interference mitigation due to operation on same or adjacent channels within the unlicensed, shared radiofrequency communication bands used with WLAN and WWAN.

At 670, the context aware radio resource management system including a concurrent wireless link optimization system may utilize a software agent to initiate communication of the selected communication type on the concurrent wireless links. In another example, types of communication may be commenced along a preferred wireless communication path between a user wireless communication device and a recipient wireless communication device in an embodiment of the present disclosure. In doing so, preferences of wireless communication device based on usage trends for a wireless communication type are taken into account in selecting either concurrent wireless link to conduct the communication. This is done in accordance with determining the preferred wireless communication links while minimizing interference or collision risk during concurrent operation by the user wireless communication device.

The request is made for access to the selected network to establish the wireless communication link. In some embodiments, the mobile information handling system operating concurrent wireless links may establish connection to each of a selection of unlicensed wireless links in a shared communication frequency band. For example, connection may be made with a WLAN AP and with a small cell WWAN substation including exchange of any necessary security access information. In another embodiment, the radio frequency subsystems of a wireless adapter may contain individual subscriber identity module (SIM) profiles for each technology service provider and their available protocols as well as a wireless access system for WLAN and similar wireless connections for any wireless links that are subscriber specific. The radio frequency subsystems may have an application processor or controller for the wireless adapter capable of switching between SIM profiles or WLAN or similar wireless network connections at the wireless communication device. Thus, a wireless link recommendation from a context aware radio resource management system including a concurrent wireless link optimization system and a context aware radio resource management system would not need to be transmitted to network broker server system, but may be selected with a SIM profile for a recommended service provider and protocol and seek direct access. Alternatively it could be submitted to a network broker server systems such as an MVNO. Nonetheless, billing and other coordination of SIM profile options may be managed by a broker such as an MVNO. The context aware radio resource management system including a concurrent wireless link optimization system and context aware radio resource management system is described further below.

FIG. 7 illustrates the context aware radio resource management system including a concurrent wireless link optimization system according to several embodiments of the present disclosure. The context aware radio resource management system 705 includes a concurrent wireless link optimization system 725 that works in connection with and may be part of the context aware radio resource management system 705. Some aspects of the context aware radio resource management system 705 are described in several embodiments in U.S. Pat. Nos. 9,088,859, 9,119,039, 9,210,714, 9,167,591 as well as several applications to the same assignee and incorporated herein by reference. The context aware radio resource management system 705 with the concurrent wireless link optimization system 725 may reside on a remote data center or may reside on a user information handling system. Portions may reside on the mobile information handling systems which seek to potentially access a plurality of concurrent wireless links. For example the concurrent wireless link optimization system 725 with aspects of the context aware radio resource management system 705 may operate within a software agent residing at the wireless communication device. Other portions of the context aware radio resource management system 705 may operate at a remote data center or a server located elsewhere.

The context aware radio resource management system 705 may have access to databases including wireless intelligence reports and traffic reports 710. Additional variations of databases available to the context aware radio resource management system 705 are discussed above and may include energy link reports, wireless link cost data and the like. Further, context aware radio resource management system 705 may also have access to user profiles 715 for the mobile information handling systems that operate as the wireless communication devices. Again, additional data may be available to the context aware radio resource management system 705 including battery power level readings, measurements of real time radio frequency QoS factors among other factors described herein or understood by those of skill.

In a distributed system where code instructions may operate on several processors, context aware radio resource management system 705 may work with components and modules via an application programming interface (API) 720 as understood by those of skill in the art. For example, coordination of code instruction modules may coordinate operation via API 720 as between the context aware radio resource management system 705 and code portions such as the concurrent wireless link optimization system 725. API 720 may further facilitate coordinated operation with a network interface driver 740, where appropriate, in a wireless communication device such as a mobile information handling system of the types described herein.

The context aware radio resource management system 705 with the concurrent wireless link optimization system 725 may include an AP/small cell substation interference module 730 executing code instructions to determine channels and interference levels from concurrently operating wireless link pairs in a wireless neighborhood. A neighboring interference list may be generated by determining the channels on which detected APs and small cell WWAN wireless links are operating. Based on operation of the AP/small cell substation interference module 730, a determination of likely interference or potential collision due to adjacency of channels or same channel operation may be assessed. From such an assessment, determination may be made regarding whether to select a different available channel or to implement interference remediation.

In some embodiments, a shared communication frequency band channel selector may be used to select a different wireless link option for concurrent operation of multiple wireless links at a wireless communication device such as a mobile information handling system. The shared band channel selector 735 may be implemented to determine a non-adjacent channel option for either of the one or more wireless protocols to be concurrently operating. The shared communication frequency band channel selector may further opt to select alternative channels for either the WLAN or small cell WWAN wireless link when a same channel occupancy is detected in some embodiments. In yet other embodiments, it may be desired to forgo all concurrent wireless link operation if the only choice is a same channel option between two wireless links. In such a situation, the context aware radio resource management system may shut down the concurrent wireless link capability. It is understood however that other options may be implemented as well including data scheduling or other collision or interference mitigation as described in embodiments herein. In some aspect, the mobile information handling system may seek to preserve concurrent wireless link capability to expand bandwidth or provide for backup wireless link options should a primary wireless link option become poorly connected or disconnected.

Network interface driver 740 may be connected to a wireless network interface device 755. Wireless network interface 755 device may operate with a shared antenna or multiple antennas for transceiving data and communications via the concurrent wireless links. The wireless network interface device 755 may operate, in an example embodiment, with a WLAN radiofrequency front end for 760 transceiving wireless data via a WLAN wireless link such as Wi-Fi. In another example embodiment, emerging 5G systems may implement small cell WWAN operation (e.g., eNodeB operations) utilizing shared communication frequency spectrum. Accordingly, a wireless network interface device 760 may also operate with a WWAN radio frequency front end 770 for transmission and reception of wireless data and communication from a small cell WWAN wireless link concurrent with the WLAN operation according to an example embodiment.

Network interface driver 740 may include a processor or controller executing code instructions for an interference or collision remediation system according to embodiments of the present disclosure. In an example embodiment, network interface driver 740 may execute code instructions for a data transmission/receiver scheduler 745. In one embodiment, a memory for queuing data may reside with code instructions for scheduling data transmission as between concurrently operating wireless links in a shared communication frequency band. One or more memory devices may be available for queuing data for the plurality of concurrently operating wireless links. For example, a WLAN queue and a small cell WWAN queue may be made available for data transmission scheduling. A data reception scheduler may also be implemented in an embodiment. In some aspects, data reception may be scheduled by transmitting requests to queue data at a BTS transmitter to limit occupancy of a channel for the wireless link.

In another example embodiment, network interface driver 740 may execute code instructions for operation of an adaptive band-pass filter 750. In one embodiment, when adjacent channels are selected for concurrent operation of wireless links, the band-pass filter applied to delineate channels may be further programmable to provide sharper delineation between the adjacent channels. Such sharper application of band-pass filtering may be conducted according implementation of band-pass filter systems of higher order than are frequently used to delineate channels in a DSP of a network interface for a wireless link protocol. The adaptive band-pass filter will reduce noise bleed over between adjacent channels caused by roll of from the ends of a channel frequency range. The adaptive band-pass filter may be implemented according to embodiments herein and as band-pass filter operation is understood by those of skill in the art.

It is understood that the block diagram of FIG. 7 may include additional components and aspects that may not all be depicted for the context aware radio resource management system 705 including a concurrent wireless link optimization system 725. Additional aspects and components including various processors, memories, busses may be utilized and the context aware radio resource management system 705 including a concurrent wireless link optimization system 725 may be a distributed system operating across multiple information handling systems according to some embodiments. Further, not all aspects of the context aware radio resource management system 705 including a concurrent wireless link optimization system 725 may be utilized in all embodiments.

FIG. 8 illustrates a method for determining a plurality of concurrent, optimal wireless links according to an embodiment. In this example embodiment, one or more wireless links may be available to a user in a wireless neighborhood as described above. Additionally, the mobile wireless communication device may utilize one or more wireless links for communication. In an example embodiment, a mobile wireless communication device may concurrently use two wireless links on a shared radiofrequency communication band. For example, a mobile wireless communication device may utilize WLAN and small cell WWAN wireless links within the shared, wireless communication band. The method of FIG. 8 may be executed via code instructions for a context aware radio resource management system including a concurrent wireless link optimization system on one or more processors or controllers. It is understood that each of the following steps may be performed by the context aware radio resource management system including a concurrent wireless link optimization system software at the wireless communication devices, at a remote location in whole or in part, or some combination of the same. For purposes of the presently described embodiment, examples of the elements of the context aware radio resource management system including a concurrent wireless link optimization system may be described in the present embodiment for explanation purposes.

At 802, the system may detect a location of the mobile information handling system that will communicate wirelessly. The location may be determined via a number of methods understood by those of skill in the art. For example, a global positioning system (GPS) may determine a longitude and latitude reading for the wireless communication device as understood by those of skill in the art. GPS may be available as a feature of the mobile communication device or may be a software application operating on the mobile information handling system. Additional location techniques may be network based via multilateration such as via interpolation of signals between base station signal antennas such as APs or signal towers for either small cell applications or wider WWAN applications in some embodiments. An example may be triangulation via advanced forward link trilateration. Another example is utilization of Wi-Fi positioning system (WPS) for a mobile information handling system within a wireless neighborhood in other embodiments. WPS may utilize RSSI and fingerprinting via APs to locate relative position to the APs. Handset based location systems determining signal strengths or cell location or Enhanced Observed Time Difference (E-OTD) system may be used in yet other embodiments.

At 804, the concurrent wireless link optimization system of the context aware radio resource management system will scan or determine available neighborhood radio WLAN options as well as any unlicensed, small cell WWAN options and other optional wireless links based on reported location of the mobile information handling system. Several shared radiofrequency communication bands may be available. In an example embodiment, wireless neighborhood options may include WLAN and unlicensed, small cell WWAN options operating on the U-NII communication band at around 5 MHz. The context aware radio resource management system including a concurrent wireless link optimization system will determine based on location of the mobile information handling system a list of APs and WWAN small cell base stations available in a neighborhood where the mobile information handling system is located. Additional wireless links not operating in a shared frequency spectrum may be assessed as optional wireless links as well.

At 806, the mobile information handling system may scan radios to determine or confirm which WLAN, small cell WWAN, or other options are online or available. The context aware radio resource management system including a concurrent wireless link optimization system may amend wireless neighborhood options that will be assessed for optimization as well as interference based on the scan of radios for available connectivity.

Proceeding to 808, the context aware radio resource management system including a concurrent wireless link optimization system may access databases remotely for access to resources or data stored there or, optionally, other data stored locally at mobile information handling system. For example, the mobile information handling system may access portions of the context aware radio resource management system including a concurrent wireless link optimization system operating on remote servers to assist in determination of optimized wireless links at the mobile information handling system location in an embodiment. Further, in some example embodiments, crowd sourced data such as wireless intelligence traffic reports 810 may be sourced from remote databases at which this data is collected in some embodiments. Similarly, in an embodiment, wireless communication device usage trend data 812 may be accessed remotely for the mobile information handling system to assess a history of data or communication usage. This data may include detailed information such as spatial temporal user profiles that show usage for the mobile information handling system for locations, users, and based on time of day or day of the week. Spatial temporal user profiles may provide somewhat reliable wireless communication device usage trend data in some embodiments in that it may capture cyclostationary trends at various locations. Additionally, wireless intelligence reports 810 and wireless communication device usage trend data 812 as well as other relevant data to the context aware radio resource management system may be accessed from locally stored memory on the mobile information handling system. In an example embodiment, tracking and storage of wireless communication device usage trend data 812 may be stored locally on the mobile information handling system in some embodiments. It is contemplated that the context aware radio resource management system may be a localized or distributed system and data sources may be both local and remote.

Upon accessing wireless intelligence reports 810 and wireless communication device usage trend data 812, as well as other data such as described with respect to FIG. 6, the context aware radio resource management system including a concurrent wireless link optimization system may determine a set of optimized wireless links for communication at 814. In an example embodiment, the set of optimized wireless links may include WLAN and small cell WWAN links for concurrent communications on a shared communication frequency band. In many cases, the context aware radio resource management system may determine that WLAN or nearby small cell WWAN links operating within an unlicensed spectrum are highly ranked optimized link options due to cost, proximity, or availability. In the case of a standalone mobile information handling system or when a connection manager is not available, the mobile information handling system may only select from the unlicensed communication bands.

The context aware radio resource management system including a concurrent wireless link optimization system software receives usage trend data relating to a common communication type used at the detected location and time of day. Upon doing so, the context aware radio resource management system including a concurrent wireless link optimization system software will determine wireless communication device usage trends based on recorded data for usage of wireless communication devices for types of wireless communication recorded as preference score data. Similarly, expressed preferences and cyclostationary data relating to device use may be accounted for in the wireless device usage trend data and preference scores.

The context aware radio resource management system including a concurrent wireless link optimization system software determines wireless communication device capabilities based on communication type. Several wireless communication device capabilities are determined. In example embodiments, the wireless communication device capabilities may include communication types available with a device, security access available to wireless systems, technology capabilities of transmitter systems, and service provider subscriptions associated with each wireless communication device. In some embodiments, smart battery management systems report battery power levels available for each of the wireless communication devices as part of the wireless communication device capabilities. Further device capabilities may also be assessed including current functions operating on the wireless communication devices that may impede or limit capabilities to operate within a communication type due to occupied RF capacity, limited processor capacity, or the like.

The context aware radio resource management system including a concurrent wireless link optimization system software then will assess wireless link ratings of available wireless links. The wireless link ratings, as described in embodiments herein, reflect QoS/capacity scores for wireless links at a detected location or probable future locations based on predicted future path of the mobile information handling system. This QoS and capacity data may be received from crowd-sourced data or measured data in accordance with the disclosure herein. The context aware radio resource management system including a concurrent wireless link optimization system will also factor in the type of transmission likely from usage trend data to generate an initial determination of wireless links that meet a threshold criteria quality rating for the wireless communication type by the mobile information handling system. Ranking factors may be weighted by cost considerations and by power consumption considerations. Power consumption ratings may be derived from energy link reports that may be crowd sourced as well and accessed by the context aware radio resource management system. Cost may be a weighting factor in other aspects when determining wireless link ratings. In some example embodiments, no cost wireless links that meet a minimum criteria of QoS, capacity, or power consumption levels may be prioritized.

In one example embodiment, the context aware radio resource management system may determine a ranked list of optimal wireless links available in a wireless neighborhood. The ranking in the list of optimal wireless links may be affected by weighting factors as described herein. Ranked optimal wireless links will be required to meet at least a minimum threshold level of QoS in one example embodiment. Weighting factors for determination of the ranked list of optimal wireless links may be established by a user or system administrator or may change dynamically. For example, weighting factors for power consumption may increasingly become relevant if the detected battery power levels fall to certain points.

In an example embodiment for energy consumption considerations, power weighting scores reflecting battery power capacity for the wireless communication devices associated with a user and reported power consumption levels for using available wireless links in energy link reports are applied. The power weighting scores may modify the wireless link quality ratings to update wireless link rating scores for each wireless link and with that may change list rankings. It is understood, the power weighting scores are but one example of weighting factors that may be applied.

At block 816, the mobile information handling system may be set up to utilize concurrent wireless links. In an example embodiment, a standalone wireless communication device having no subscriber capabilities with licensed WWAN communication protocols may establish concurrent wireless links to enhance bandwidth. The concurrent wireless link optimization system of the context aware radio resource management system determines candidate pairs of concurrent wireless links from the list of optimal wireless links defined above. In an example embodiment, the mobile information handling system will set up concurrent wireless links from two protocols. For example, one WLAN wireless link and one small cell WWAN link may be the intended concurrent wireless link set up. The concurrent wireless link optimization system will select a pair of candidate wireless links listed in the optimal wireless links for assessment of interference or data collision. In one example embodiment, the concurrent wireless link optimization system may select the two most highly rated wireless links initially. For a standalone mobile information handling system this is likely limited to wireless links operating in unlicensed communication bands. As the concurrent wireless link optimization system iterates through the potential concurrent wireless link pairs, it may select lower rated wireless link pairs with each iteration. It is understood however, selection of candidate pairs of concurrent wireless links may be selected in any order from the list of optimized wireless links in other embodiments. The concurrent wireless link optimization system will assess each pair of optimal wireless links to provide a localized interference rating for each pair. The interference rating may not overcome the quality rating for each individual wireless link in the pair; however a high risk of interference or data collision will reduce the rating of such a pair unless interference mitigation measures are implemented. As each pair is assessed it may be added to an interference ranking list of candidate concurrent wireless link pairs.

At 820, the concurrent wireless link optimization system will model or measure the total potential interference between the selected candidate pair of wireless links that are operating in the same band. In an example embodiment, potential interference or collision is measured or modeled based on the channels within the shared communication frequency band on which each concurrent wireless link would operate. In a particular embodiment, a determination may be made of the operating channels for each WLAN AP or small cell base station for WWAN in the selected pair of potential concurrent wireless links. The concurrent wireless link optimization system will determine if the candidate pair of potential concurrent wireless links will operate on the same channel within, which represents the greatest potential risk of interference at 822. Proceeding to 824, if the selected pair of candidate concurrent wireless links are not operating on the same channel, the concurrent wireless link optimization system will determine if the selected candidate pair will operate on adjacent channels, which represents some risk of radio interference. Based on the determination of whether a selected candidate pair of potential concurrent wireless links are on the same channel or adjacent channels, a pair interference rating is provided and compared to other available pairs of candidate concurrent wireless links. At 826, this pair rating will be added to an interference ranking of candidate concurrent wireless links from the list of optimal wireless links.

As described, it is often the case that wireless link rating are preferable for WLAN or small cell WWAN wireless links if available in the wireless neighborhood. However, when a pair of potential concurrent wireless links will operate on the same channel within a shared communication frequency band, the risk of collision and interference is increased. Accordingly, such a candidate pair may receive a poor interference rating. Similarly, measurement or modeling may show that adjacent channel pairs of concurrent wireless links are also subject to higher potential interference due to concurrent operation from the same mobile information handling system and in some embodiments the same antenna. Accordingly, these adjacent channel candidate concurrent wireless link pairs may receive a lower rating than concurrent wireless links operating on non-adjacent channels. It may be the case however that the only unlicensed spectrum options available or of sufficient quality within a wireless neighborhood within range of a mobile information handling system are on the same or adjacent wireless links. If so, selection of a same-channel or adjacent pair may still occur by the context aware radio resource management system including the concurrent wireless link optimization system.

At decision block 826, the concurrent wireless link optimization system determines if additional pairs of candidate concurrent wireless links are to be assessed from the list of optimized wireless links determined from above. If so, flow proceeds back to 816 to select another pair of candidate concurrent wireless links for interference assessment. If not, flow proceeds to 830.

At 830, the concurrent wireless link optimization system will select a channel pair of concurrent wireless links for communication. In an example embodiment, the selected pair of concurrent wireless links may be from a WLAN protocol (Wi-Fi) and from a small cell WWAN protocol (eNodeB). The selected channel pair of concurrent wireless links are determined based on a combination of QoS rating for optimal links as described above relative to the interference rating and its impact on that QoS rating for the pair.

The selection of the pair of concurrent wireless links may be made according to several factors. The concurrent wireless link optimization system may disallow same channel operation in some embodiments. In such embodiments, another concurrent wireless link pair must be selected. Alternatively, concurrent operation of wireless links may be shut down if only same channel operation is available.

In other example embodiments of selecting concurrent wireless link pairs from the rated list of optimal wireless link pairs, the concurrent wireless link optimization system may elevate pairs without adjacent channel operation above those with slightly higher QoS or other optimization rating on adjacent channels to avoid adjacent channel interference in other example embodiments. However, in some embodiments the concurrent wireless link optimization system may be left with same channel or adjacent channel concurrent wireless link pairs having far superior QoS ratings than for other pairs. Selection is made depending on how much impact a determination of same channel or adjacent channel operation will have. This may further depend on the interference mitigation measures available. A pair of concurrent wireless links may be selected for communication according to which pair has the highest combined QoS or other optimization ratings, but also that pair with the lowest potential interference or probability for data collision. In some example embodiments, a balance is struck by determining a threshold level of difference between QoS or other combined optimization rating between available concurrent wireless link pairs above which an adjacent channel pair may be tolerable relative to the lower combined QoS rating of a non-adjacent pair in one example embodiment. Similarly, another balance may be struck by determining a threshold level of difference between QoS or other combined optimization ratings between available concurrent wireless link pairs at which an same channel pair may be tolerable relative to a lower combined QoS rating at a non-same channel pair in another example embodiment. In some embodiments, the tolerance threshold level may be the same level for both. In other embodiments, the tolerance threshold levels may be different for adjacent channels and same channel concurrent operation. For example, the tolerable difference in combined QoS optimization level of a non-same channel pair may substantially larger in that a lower QoS level may be tolerable compared to selecting the same channel concurrent wireless link pair.

At 832, the concurrent wireless link optimization system in an embodiment may determine if a pair of concurrent wireless links selected for communication are on the same channel. If the concurrent wireless links are on the same channel, flow proceeds to 834 where the mobile information handling system may implement a data scheduler for either data transmission, receiving data, or both. The transmitter data scheduler for the mobile information handling system may implement one or more queues for each concurrent wireless link and time the data transmissions such that the two selected protocols do no operate simultaneously on the shared wireless communication channel. The data scheduler may be used to avoid data collision on the shared channel between the concurrent wireless links. Data scheduling may be conducted according to alternating order. In some embodiment, every other byte of data may be transmitted between the concurrent wireless link protocols such as in a round robin transmission scheduling algorithm. Other algorithms are also contemplated for data scheduling including spurts or groups of data bytes for transmission within a round robin alternating among each group of bytes between concurrent wireless links in a modified round robin system in a different embodiment. For example, the size grouping differ for each side of the concurrent wireless links depending on the quality or bandwidth of each side of the concurrent pair. Other types of scheduling may be implemented as well in other embodiments. Data on the higher QoS wireless link between the pair of concurrent wireless links may be prioritized to transmit more frequently or more data bytes per turn in a modified round robin type of scheduling algorithm in other aspects. In yet other embodiments, data priority may yield a scheduling order. For example, use of data tags may cause a data scheduler to transmit higher priority data such as video, audio, or voice data subject to significant reduction in user experience ahead of other types of data. The data tags may place data to be transmitted into a plurality of priority categories including medium level data transmission such as for web browsing, email, or text and a low priority such as for bursty data, back up data transfers, and the like. A device data scheduler may further activate higher order error code correction schemes for wireless links that are characterized by high interference and lower QoS metrics to help reduce transmission on these links.

In another embodiment, a data source transmitter may be subject to data scheduling. The mobile information handling system may signal the data source transmitter or transmitters for the concurrent wireless links to schedule transmissions of data on the concurrent wireless links such that no simultaneous transmission on the same channel occurs. Similar data transmission scheduling may be implemented by a data source transmitter to that described above for the transmission from a mobile information handling system.

If the selected pair of concurrent wireless links will not operate on the same channel, flow proceeds to 836. At 836, the concurrent wireless link optimization system in an embodiment may determine if a pair of concurrent wireless links selected for communication are on adjacent channels. If the selected concurrent wireless links are not on adjacent channels, then the flow may end and no interference mitigation is implemented.

If the selected concurrent wireless links are determined to be on adjacent channels, flow proceeds to 838. At 838, the mobile information handling system may implement interference mitigation measures when the selected concurrent wireless links will operate on adjacent channels.

In one example embodiment (not shown), flow could proceed to implement a data scheduler function described above as between adjacent concurrently operating channels. Use of a data scheduler on adjacent channels would reduce interference between those channels in that simultaneous transmission on those adjacent channels could be avoided reducing interference during active operation on both adjacent channels. A data scheduler for transmission of data, receiving data, or both could be implemented in accordance with discussion of the embodiments described herein.

In another embodiment, the mobile information handling system may implement an adaptive band-pass filter at 838 to sharpen the defined channel width and reduce bleed over of radiofrequency noise from shoulders of the transmission channel into the adjacent channels. Although a sharper adaptive band-pass filter may create noise via harmonics for other channels upon implementation, that noise is less that the reduction in noise on adjacent channels concurrently operating from the same mobile information handling system.

The adaptive band-pass filter may be implemented according to techniques understood and implemented in an RF front end digital signal processor (DSP). In an example embodiment, the adaptive band-pass filter may be a modified version of the fixed band-pass filters used in digital signal processors for radiofrequency front end circuitry for a given protocol. Radiofrequency front end circuitry is operatively connected to an antenna and may include front-end digital signal processing to determine or define channels and bands within which radios may operate. The DSP will frequently include fixed, or near fixed band-pass filters defining channels of operation within a designated communication frequency band. Wireless link modems deployed frequently are set with respect to band-pass operation defining channels to limit harmonic noise while sufficiently defining a channel width. These band-pass filters are often an 8^(th) order band-pass filter having a lower order or fewer poles and zeroes than a sharper band-pass filter option. These lower order band-pass filters provide a sufficient channel width of frequency but potentially have shoulders or roll off at the ends of the channel frequency width that bleed over into adjacent channels within the same communication band. With transmission and reception on channels from transceivers sufficiently spaced apart, this bleed over impact is lowered. However with concurrently operating wireless links transceiving from the same mobile information handling system, and potentially from the same antenna in some embodiments, the risk of interference from bleed over is higher.

It is understood that the programmable band-pass filter of the present embodiment may be modified to a higher order band-pass filter. In an example embodiment, a Chebyshev-1 band-pass filter may be implemented in place of the normal lower order band-pass filter when adjacent channel pairs are used for concurrent wireless links. Although a Chebyshev-1 type filtering would incur a cost of noise harmonics, potentially across a wider group of channels in the shared communication frequency band, the reduction of bleed over noise from the roll off at the ends of the channel frequency range into the adjacent channels would compensate for this trade off. During operation when non-adjacent channels are used as concurrent wireless links, normal lower-order band-pass filtering may be applied. The Chebyshev-1 type filter is but one example type of higher order filter that may be implemented in any type of higher order band-pass filter may be implemented by those of skill in various embodiments.

The present embodiment proposes addition of programmable logic to the DSP to permit adjustment of the band-pass filter to a higher order for a given channel to enable it to be sharpened during detected adjacent, concurrent wireless link channel operation. In addition to the DSP in the front-end radio frequency circuitry, the wireless link protocol modem may include an application processor for control of the modem and RF transmission including encryption security and other function of transmitting data and communications wirelessly. RF baseband processing may also be included for understood functions such as modulation and demodulation of signals according to protocols to reveal the data signal and a modem application processor.

The above example embodiment of FIG. 8 is not limited to concurrent wireless links that include one WLAN and one small cell WWAN wireless link. It is contemplated that two WLAN links, two small cell WWAN wireless links or other concurrent wireless links operating within a shared communication frequency band may be selected according to the above method. Further, the example embodiment of FIG. 8 refers to selection of potential pairs of concurrent wireless links, but it is contemplated that the above algorithm could be applied to trios of concurrent wireless links or an even greater set of wireless links desired for concurrent operation by a mobile information handling system. The algorithm of FIG. 8 may be readily applied by those of skill to a trio or greater number of concurrent wireless links for a mobile information handling system.

It is understood that the methods and concepts described in the algorithm above for FIG. 8 may be performed in any sequence or steps may be performed simultaneously in some embodiments. It is also understood that in some varied embodiments certain steps may not be performed at all or additional steps not recited in the above figures may be performed. It is also contemplated that variations on the methods described herein may also be combined with portions of any other embodiments in the present disclosure to form a variety of additional embodiments.

FIG. 9 illustrates another method for determining a plurality of concurrent, optimal wireless links according to an embodiment. In this example embodiment, one or more wireless links may be available to a user in a wireless neighborhood as described above. Additionally, the mobile wireless communication device may utilize one or more wireless links for communication. In an example embodiment, a mobile wireless communication device may concurrently use at least two wireless links on a shared radiofrequency communication band. For example, a mobile wireless communication device may utilize WLAN and small cell WWAN wireless links within the shared, wireless communication band. In a further example embodiment, the mobile wireless communication device may be a standalone mobile information handling system with only unlicensed wireless communication bands available. The method of FIG. 9 is not limited to the above wireless link protocols however.

The method of FIG. 9 may be executed via code instructions for a context aware radio resource management system including a concurrent wireless link optimization system on one or more processors or controllers. It is understood that each of the following steps may be performed by the context aware radio resource management system including a concurrent wireless link optimization system software at the wireless communication devices, at a remote location in whole or in part, or some combination of the same.

At 902, the context aware radio resource management system including a concurrent wireless link optimization system may begin by assessing the number of neighboring WLAN APs in a wireless neighborhood. For each AP or unlicensed small cell WWAN substations, flow proceeds to 904 where the concurrent wireless link optimization system will assess the device frequency for the WLAN APs and determine an operating frequency for that wireless link option. An example includes the neighboring interference list described above with respect to FIG. 3.

At 906, the context aware radio resource management system including a concurrent wireless link optimization system may begin by assessing the number of neighboring unlicensed small cell WWAN substations in a wireless neighborhood. In an embodiment, the small cell WWAN substations may be referred to as Femtocells. For each unlicensed small cell WWAN substation, the concurrent wireless link optimization system will assess the device frequency for the small cell substation and determine an operating frequency for that wireless link option. An example includes the neighboring interference list described above with respect to FIG. 3.

For each small cell WWAN substation and WLAN AP, flow will proceed to 908 to determine levels of potential intra-device interference with the WLAN AP for candidate concurrent wireless links that may be selected. This assessment may be conducted pair by pair in an example embodiment. It is understood that intra-device interference could also be conducted trio by trio or by other grouping of concurrent wireless links in some embodiments. In the example embodiment, pairs of possible concurrent wireless links are assessed for same channel or adjacent channel operation. An algorithm similar to above may be used to determine whether the concurrent wireless link pair utilizes a same channel or adjacent channels. In an embodiment, the concurrent wireless link pairs may model anticipated interference based on the channel defining band-pass filter operation, frequency range of the operating channels, location, power required to transmit, and operation overlap as understood and described with references to embodiments in the disclosure herein.

At 910, the concurrent wireless link optimization system may also assess potential interference among neighboring APs for the candidate unlicensed small cell WWAN substation and the candidate AP under consideration by similarly modeling interference based on adjacent or same channel operation, proximity, power of transmissions, and operation overlap. During set up of wireless neighborhoods, determination of overlapping channel usage when locating APs or unlicensed small cell WWAN substations may not be coordinated in the wireless neighborhood. This potential interference between APs and unlicensed small cell WWAN substations in the wireless neighborhood is modeled and may factor into selection of a concurrent wireless link pair in some embodiments. Anticipated noise from use of APs or unlicensed small cell WWAN substations in the neighborhood would reach a threshold level in some embodiments to reduce the anticipated QoS of those wireless links sufficiently to lower their ranking in a list of optimized wireless link pairs for concurrent operation in an embodiment.

At 912 in some embodiments, a total interference factor for both intra-device concurrent wireless link operation and interference at the BTS stage due to usage of neighboring APs or unlicensed small cell WWAN substations is determined. Total interference factor is determined based on the assessment of interference on both the mobile information handling system side and BTS side of a pair of wireless links. In some embodiments, actual interference may be measured during concurrent operation of the wireless link pairs. In other embodiments, modeling based on understood interference factors may be sufficient to determine the overall interference on both sides of the wireless link pair under assessment.

At 914, the concurrent wireless link optimization system will determine if any additional candidate unlicensed small cell WWAN substation wireless links for concurrent operation remain to be analyzed for interference. If so, flow returns to 906 to analyze or model interference of a next pair of candidate wireless links in the shared communication frequency band including the next unlicensed small cell WWAN substation in the wireless neighborhood of the mobile information handling system. Similar to the embodiments described herein for interference or collision assessment, the process repeats to determine a rating factor for interference anticipated when selecting each candidate pair of wireless links for concurrent operation.

If not, flow proceeds to 916 which will determine whether all APs in a wireless neighborhood of a mobile information handling system have been assessed for channel frequency operation and potential intra-device interference and BTS interference within the shared communication frequency band. If not all detected APs in the wireless neighborhood have been assessed, flow returns to 902 iteratively to assess the next AP. Then the method will iteratively select another candidate unlicensed small cell WWAN substation for pairing with the next AP as a candidate concurrently wireless communication pair and proceed as previously described.

If no additional APs are to be assessed meaning no additional concurrent wireless link pairs must be analyzed for interference or collision risk, then flow proceeds to 918. At 918, the concurrent wireless link optimization system may select a WLAN wireless option and a small cell WWAN wireless link option for concurrent operation. The candidate selection will be made based on having low risk of interference between the wireless links in the pair. The lowest interference may be based solely on intra-device WLAN wireless and small cell WWAN wireless link interference in some embodiments. The lowest interference may be based solely on BTS interference determined for the WLAN wireless and small cell WWAN wireless link in some embodiments. In yet other embodiments, the lowest interference may be based on total interference factors between intra-device WLAN wireless and small cell WWAN wireless link pair for concurrent wireless link operation.

In the present embodiment at 918, the context aware radio frequency management system may select the concurrent wireless link pair with a lowest interference level. This candidate concurrent pair with lowest interference may then be assessed as to whether it has a sufficient QoS rating by the context aware radio resource management system to be acceptable for wireless link operation. Additional factors including power consumption, battery state, cost, and usage trend data determining the type of expected data communication will factor into rating each link of the pair of concurrent wireless links under the context aware radio resource management system according to embodiments described herein. If one of the pair of concurrent wireless links does not meet a threshold rating such as a threshold QoS level, then that lowest risk of interference pair is rejected, and the next lowest risk concurrent wireless link pair is selected. The assessment by the context aware radio resource management system to determine QoS or related optimization ratings for each side of the wireless link pair may be assessed for the next concurrent wireless link pair for sufficiency of their optimization ratings. Weighting factors as described in several embodiments above may be employed by the context aware radio resource management system in deriving optimization ratings at each iteration in some embodiments.

In another embodiment, a selected group of candidate pairs of wireless links for concurrent operation having lower interference determination at 918 may be assessed for optimization ratings (QoS, usage, power consumption, or cost, etc.) by the context aware radio resource management system. A threshold level of interference determination above which wireless link pairs are not considered may be set. In such an embodiment, a selection from the candidate wireless pairs for concurrent operation may be made based on a highest average optimization rating between the two wireless links in the pair. In other embodiments, the pair selection may be made on other grounds such as determination that all selected pairs have sufficiently high optimization ratings and low interference to select a concurrent wireless pair that does not operate on a same channel or an adjacent channel if that option is available. In some cases, a concurrent wireless link pair may still be selected however that operates on a same channel or adjacent channels within the shared communication frequency band due to limited selection or substantially better QoS or link availability options.

Flow proceeds to 920 to determine if selected wireless link pairs (e.g., a WLAN and small cell WWAN pair) operate on identical radio channels within the shared communication frequency band. If not, flow proceeds to 928 to determine if the selected wireless link pair operates on adjacent channels within the shared communication frequency band.

If the selected wireless link pair does operate on an identical channel however, flow proceeds to 922. At 922, the context aware radio resource management system with concurrent wireless link optimization will determine if another available pair of acceptable wireless links may be selected instead of concurrent wireless links operating on a same channel. If another acceptable set of concurrent wireless links for WLAN and unlicensed small cell WWAN that that will not operate on the same channel is available, then the selected wireless link pair may be rejected and the flow may proceed to 926 to select that pair is selected for concurrent communication. Flow will then proceed to 928 to determine if the next-selected wireless link pair operates on adjacent channels within the shared communication frequency band.

At 928, the context aware radio resource management system with concurrent wireless link optimization may determine that the selected concurrent WLAN and unlicensed WWAN wireless links are not operating on adjacent channels in the shared communication frequency band. If the selected pair of concurrent wireless links are not operating on adjacent channels, flow proceeds to 932 where the optimized, concurrent wireless link pair that is selected is activated. The wireless adapter and the context aware radio resource management system will establish and schedule data transmission over the selected concurrent WLAN and unlicensed WWAN wireless links. If, however, the selected pair of concurrent wireless links are operating on adjacent channels at 928, flow proceeds to 930 to implement an adaptive band-pass filter to reduce interference as between concurrently operating adjacent channels within the shared communication frequency band. At 930, the context aware radio resource management system including a concurrent wireless link optimization system may activate adaptive band-pass filtering between the adjacent channels to reduce potential overlap interference. The adaptive band-pass filter may activate a higher order band-pass filter in a DSP of front end radio circuitry for the two concurrently operating wireless link protocol radios. The adaptive band-pass filter may operate according to embodiments described above to sharpen the frequency range of each of the defined adjacent channels. It is understood that according to the adaptive band-pass filter descriptions above, a variety of higher order filters may be implemented for a period of time when concurrent and adjacent channel operation occurs. It is understood that the adaptive band-pass filtering may be executed via programmability logic in the DSP band-pass filtering function and may be implemented in accordance with embodiments described herein.

In some example embodiments, a data scheduler may be used instead of or in addition to the adaptive band-pass filter at 930 to mitigate interference between adjacent channels (not shown). The data scheduler may operate in accordance with embodiments described above to implement round-robin operation, modified round-robin operation, or to prioritize data by levels and schedule data transmission or receipt based on the priority levels. Several embodiments are described herein to implement the data scheduler. Upon determining that the concurrent WLAN and unlicensed WWAN wireless links will operate on adjacent channels with application of an adaptive band-pass filter at 930, flow may proceed to 932 where the optimized, concurrent wireless link pair is activated. The context aware radio resource management system and the mobile information handling system wireless adapter may schedule to transmit data on the selected concurrent wireless links.

Returning to 922, if no alternative pair of acceptable wireless links may be selected instead of the selected concurrent wireless links operating on a same channel, flow may proceed to 924. At 924, the concurrent wireless link optimization system may activate collision or interference mitigation. In an example embodiment, the collision mitigation may include activating a scheduler to alternate transmission between the concurrent wireless links operating on the same channel within the shared wireless communication band. The data transmission scheduler system is described above in several embodiments. Sequential radio transmissions or reception may be scheduled as between the concurrent WLAN and unlicensed small cell WWAN pair in some embodiments. In other embodiments, round robin scheduling, modified round robin scheduling, or data priority scheduling may be implemented. In another embodiment, if no alternative pair of acceptable wireless links is available at 922, the concurrent wireless link optimization system may opt to deactivate one of the concurrent wireless links rather than risk data collision by operation on the same channel.

In an example embodiment, the mobile information handling system may deactivate the small cell unlicensed radio channel since it may provide for fewer wireless link options or may serve in some embodiments as a supplemental wireless bandwidth to a WLAN wireless link. Deactivation of one concurrent wireless link may also serve as an interference mitigation measure. In other embodiments, the WLAN option may be deactivated. Deactivation may occur in some embodiments due to the unacceptable aspect of potential data collision during same channel operation.

Upon determining that both the WLAN and unlicensed WWAN wireless links will operate concurrently on a same channel via a data scheduler at 924, flow may proceed to 932 where the context aware radio resource management system and the mobile information handling system wireless adapter may schedule to transmit data on the concurrent wireless links. If deactivation of one concurrent wireless link has occurred, only the other active wireless link may be scheduled for data transmission at 932.

The mobile information handling system may thereby maximize usage and bandwidth on unlicensed, shared communication frequency bands for transmission of data according to the above. Typically these unlicensed, shared communication frequency bands are lower cost and may have high availability or bandwidth when QoS objectives are met. Thus, maximizing utilization with concurrent wireless links with lower risk of interference provides a benefit to the mobile information handling system operation. At this point, the process may end.

The above example embodiment of FIG. 9 is also not limited to concurrent wireless links that include one WLAN and one small cell WWAN wireless link. It is contemplated that other combinations of concurrent wireless links operating within a shared communication frequency band may be selected according to the above. Further, the example embodiment of FIG. 9 refers to selection of potential pairs of concurrent wireless links, but it is contemplated that the above algorithm could be applied to trios of concurrent wireless links or an even greater set of wireless links desired for concurrent operation by a mobile information handling system. The algorithm of FIG. 9 may be readily applied by those of skill to a trio or greater number of concurrent wireless links for a mobile information handling system.
